EO
Error out
Charge pump output pin of phase detector built into a PLL. If a divided oscillator frequency is higher than the reference frequency, the output of this pin goes high. If the divided oscillator frequency is lower, the output goes low. If the divided oscillator frequency agrees with the reference frequency, the output enters the floating state. Power-supply pin of the device This pin supplies a voltage of 5 V 10 % while the device is operating. The rise time (0 to 4.5 V) of VDD must not exceed 500 ms. If the rise time is significantly long or if the voltage falls below the operating voltage but is between 0 V and 3.5 V, the state of an initial setting diode switch may be read incorrectly. Input pin of the local oscillator output (VCO) in the AM (MW, LW) band When tuned to broadcasts in the MW or LW band, this pin becomes active. Otherwise, the pin is internally pulled down. To protect the built-in AC amplifier, block the flow of direct current with a capacitor, then input the frequency. Input pin of the local oscillator output (VCO) in the FM band When tuned to broadcasts in the FM band, this pin becomes active. Otherwise, the pin is internally pulled down. Because an AC amplifier is incorporated, block the flow of direct current with a capacitor, then input the frequency. Input pin of the device selection signal Always pull up the pin.

Initial setting diode AUTOLOC Description This switch specifies the local function, as follows: AUTOLOC 0 Local function Either or DX mode is selected according to a key entry (no auto local function available). Each time the MONO/LOC key is pressed, switching occurs between local and DX modes. The local output is high in the local mode during auto-tuning (seek, scan, or auto-store). The auto local function is performed (if available). The MONO/LOC key becomes ineffective. Keeping the SEEK UP , SCAN UP , SCAN DWN or P.SCAN key for at least 2 seconds triggers auto-tuning, turns on the "LOC" display, and makes the local output high. After one cycle of auto-tuning is completed, a search begins in DX mode (with the "LOC" display off and local output at a low level). In modes other than auto-tuning , the "LOC" display is off and the local output is low. If a key for the same operation (for example, the SEEK UP key during seek operation) is pressed in local mode during auto-tuning, a search begins in DX mode at the same frequency used when auto-tuning began. If the key is pressed in DX mode, auto-tuning stops, and the frequency that was selected when auto-tuning began is reselected. The same operation as above occurs when the AUTO500 is set to 1 (by keeping the MAN UP or MAN DWN key pressed for at least 0.5 seconds).

Momentary key MAN UP MAN DWN Description The MAN UP and MAN DWN keys are used to increment and decrement the reception frequency in radio mode, respectively. During clock display, they are also used in connection with the DISP key to adjust the clock. They are again used to increase/decrease the volume of sound during electronic volume control if VKYSEL = 1. (1) In radio, radio-monitor tape, and radio-monitor CD modes Either of the following operations occurs depending on the state of the AUTO500 initial setting diode. AUTO500 0 Description Each time the MAN UP or MAN DWN key is pressed, the frequency counter is incremented ( MAN UP key) or decremented ( MAN DWN key) by one step (one channel space). Keeping the key pressed for at least 0.5 seconds speeds the increment/decrement to a rate of one step per 50 ms. Each time the MAN UP or MAN DWN key is pressed, the frequency counter is incremented ( MAN UP key) or decremented ( MAN DWN key) by one step (one channel space). Keeping the MAN UP key pressed for at least 0.5 seconds triggers a seek operation in seek-up mode. This seek operation is the same as that triggered by the SEEK UP key.

(1: Shorted by the diode; 0: Open) (2) While " " is displayed in tape mode or " " is displayed in CD mode The MAN UP and MAN DWN keys are ineffective. (3) During clock display While the DISP key is held pressed during clock display, pressing the MAN UP and MAN DWN keys enables adjusting the minute and hour displays, respectively. See the description of the DISP key for how to adjust the minute and hour displays. (4) When the electronic volume control function is effective and VKYSEL = 1: The MAN UP and MAN DWN keys are used to adjust (increase and decrease) the volume of sound in the electronic volume control mode selected using the VOL SEL key. Once an electronic volume control mode is selected using the VOL SEL key, the MAN UP and MAN DWN keys function in the same way as the VOL UP and VOL DWN keys. In a mode other than an electronic volume control mode, the MAN UP or MAN DWN key does not function as a volume control. Pressing the MAN UP key works for each electronic volume control mode as follows: Mode Volume Bass Treble Balance Fader Function Increases the main sound volume. Increases the bass.

Decreases the bass. Decreases the treble. Emphasizes the sound volume from the left-side speaker. Emphasizes the sound volume from the rear speaker.
MONO/LOC
The MONO/LOC key controls MONO (monaural)/STEREO mode and local (local/DX) mode. (1) Monaural mode control When this key is pressed and held down for two seconds or more, MONO and STEREO modes can be switched. The key is effective, when the current mode is radio, radio-monitor CD, or radio-monitor tape mode and the FM or MW band is selected. (For the MW band, the key is effective if the MWS initial setting diode = 1 and the tuner has a stereo capability.) Each time the key is pressed, switching occurs between MONO and STEREO modes. The following table lists MONO/STEREO mode and the states of the "ST" display and "MONO" display. MONO/ STEREO mode MONO STEREO "ST" display Does not light Lights "MONO" display Lights Does not light
(2) Local mode control The key is effective when the current mode is radio, radio-monitor CD, or radio-monitor tape mode and when AUTOLOC initial setting diode = 0. Each time the key is pressed, switching occurs between local and DX modes (only when the key is released within two seconds). The following table lists local/DX mode, the state of the "LOC" display, and LOC pin output. Local/DX mode LOCAL DX "LOC" display Lights Does not light LOC pin High levelNote Low level
Note A high level is output only during auto-tuning. The LOC pin is always at a low level during a tuning type other than auto-tuning. See the description of the LOC in Chapter 1. MTL The MTL key controls MTL (METAL) mode. It is effective when the current mode is radio or radiomonitor tape mode. Each time the key is pressed, METAL mode is switched on or off. The following table lists METAL mode on/off, the states of the "METAL" display, and METAL pin output. METAL mode ON OFF "METAL" display Lights Does not light METAL pin High level Low level

Momentary key MUTE Description The MUTE key controls the electronic volume control mute function. Pressing the MUTE key in a mode other than mute mode selects mute (silent) mode. In mute mode, the volume value is displayed, and the display is caused to blink. The mute function is reset under the following conditions. When an effective key other than the DISP key is pressed When the mode is changed When a station is detected during a seek or scan operation, with the MUTE pressed. When the MUTE key is pressed during muting The POWER key is used to control the power-on/off of the radio in momentary key mode. It is effective when the IGNITION pin is at a high level. Pressing this key inverts the output of the POWER pin. When the POWER pin output is set to low (the power is turned off), the tape recorder, CD player and radio are forced to be turned off even when they have been in the power-on state. In this case, they are turned off with or without clock display, according to whether they were in clock mode or non-clock mode. The power-on mode varies as follows according to the state of the RDSET, TPSET, and CDSET switches. Mode Radio mode Tape mode CD mode Caution REDSET ON ON/OFF ON/OFF TPSET OFF ON ON/OFF CDSET OFF OFF ON
POWER
At the initial power-on, the POWER pin outputs the high level. When the level of IGNITION pin changes from low to high, the POWER pin outputs the level which have been set before IGNITION becomes low, until the primary power supply is turned off.
P.SCAN
This key functions as a preset scan and auto-storage key. The operation triggered by the key varies depending on the state of the DISAMEMO initial setting diode. (1) When DISAMEMO = 0 (with the auto-storage function): The operation varies depending on the timing at which the key is operated. (a) If the key is released within 2 seconds: The preset scan operation begins immediately when the key is released. (b) If the key is pressed for at least 2 seconds: The auto-storage operation begins when 2 seconds elapse. (2) When DISAMEMO = 1 (without the auto-storage function): The preset scan operation begins immediately when the key is pressed. The preset scan and auto-storage functions are described below. Preset scan operation The contents of each preset memory are called for 5 seconds each time automatically. If a frequency other than those in the preset memories is being received, calling begins at M1. If a frequency recorded in a preset memory is being received, calling begins at the preset memory numbered one higher than that preset memory (for example, at the M4 preset memory if a frequency recorded in the M3 preset memory is being received). This operation is illustrated below. Example If the FM1 band is being received:

PD17012GF-058
Momentary key P.SCAN Description The same operation occurs for the MW (MW1 and MW2) and LW bands. When the next preset memory is accessed after a 5-second hold period, a beep is generated. During each 5-second period, the preset memory number display blinks at 1 Hz (with a duty cycle of 50%). The "CH" display does not blink. To stop preset memory scanning during a 5-second hold period, press the P. SCAN key again or a preset memory key that corresponds to the preset memory being currently accessed. It is possible to write to a preset memory when another preset memory is on hold (for example, write to the M5 when the M1 is on hold). When a write operation is completed, the preset scan operation ends. Hold down one of the M1 to M6 keys for at least 2 seconds during the preset scan operation. The frequency currently being received is written into the preset memory corresponding to the pressed key. The preset scan operation ends immediately when any of these keys is pressed. During the preset scan, each key functions as follows: Key P.SCAN SCAN UP SCAN DWN SEEK UP MAN UP MAN DWN BAND Description The scan operation stops, and the current frequency is received. The scan operation stops, the operation corresponding to the pressed key begins at the frequency being currently received.
In radio, radio-monitor tape, and radio-monitor CD modes, the scan operation stops, and the operation corresponding to the pressed key begins at the frequency being currently received. Either of the following operations occurs depending on what the current mode is. (1) In radio mode The scan operation continues. The RDMONI key becomes ineffective. (2) In radio-monitor tape and radio-monitor CD modes The scan operation stops, and the operation corresponding to the pressed key begins at the frequency being currently received. The scan operation continues. The operation corresponding to the pressed key begins.

Momentary key P.SCAN Description Auto-storage function Broadcasting stations are searched for automatically. The frequency of a detected station is written to a preset memory. A method used to detect a station is determined according to the states of the ENAMIF and ENFMIF initial setting diodes. A broadcasting station search begins at the frequency being currently received and is performed through the frequencies in the ascending order. When a station is detected, its frequency is written to a preset memory. For the voltage with SD, see the description of the SD in Chapter 1. The auto-storage operation varies depending on the state of the AUTOLOC initial setting diode as follows: (1) When AUTOLOC = 0 (with no auto local function): The auto-storage function varies depending on which mode has been selected, local or DX, when the function begins. (a) If DX mode has been selected when the auto-storage function starts: A search beings at the frequency being currently received and continues in the ascending order of the frequency. When all frequencies are searched through, the search operation ends. If the P. SCAN key is pressed during the search operation, the auto-storage operation ends, and the frequency selected when the auto-storage operation began is received. When all frequencies are searched through, if at least one station is detected, the contents of the preset memories are updated, and the preset scan begins at the M1 preset memory. How the contents of the preset memories are updated varies depending on the number of stations detected. If six or more stations are detected: If six or more stations are detected, six stations with a higher SD input are selected and written to the preset memories. A lower frequency is written to a lower-numbered preset memory. If less than six stations are detected: If less than six stations are detected, lower frequencies are written to lower-numbered preset memories. The contents of a preset memory will not be changed if there is no frequency corresponding to it. (b) If local mode has been selected when the auto-storage function starts: A search begins in local mode at the frequency being currently received and continues in the ascending order of the frequency. When all frequencies are searched through, if six or more stations are not detected, the search switches to DX mode and continues in it. If six or more stations are detected in local mode, or all frequencies are searched through in DX mode, the auto-storage operation ends. Pressing the P. SCAN key during the search operation stops the auto-storage operation, and causes the frequency selected when the auto-storage memory began to be received. If six or more stations are detected in local mode, or all frequencies are searched through in DX mode, the auto-storage operation ends. If at least one station is detected, the contents of the preset memories are updated, and the preset scan begins with the M1 preset memory. How the contents of the preset memories are updated varies depending on the number of stations detected, as follows: If six or more stations are detected in local mode: If six or more stations are detected, six stations with a higher SD input are selected and written to the preset memories. A lower frequency is written to a lower-numbered preset memory If less than six stations are detected in local mode and some are detected in DX mode, resulting in a total of six or more stations being detected: Stations detected in DX mode with higher SD input levels are selected and added to the number of stations detected in local mode so that the total becomes six. In this case, the stations detected in local mode are excluded from those detected in DX mode. The frequencies of the six stations are written to the preset memories, with a lower frequency written to a lower-numbered preset memory.

PD17012GF-058
Momentary key P.SCAN Description If less than six stations are detected in local mode and some are detected in DX mode, resulting in a total of less than six stations being detected: If the same station is detected in DX and local modes, the station detected in DX mode is deleted so that the same frequency will not be written to two preset memories. The frequencies of the less than six stations detected are written to the preset memories, with a lower frequency written to a lower-numbered preset memory. The contents of a preset memory will not be changed if there is no frequency corresponding to it. (2) When AUTOLOC = 1 (with the local function): A search begins in local mode at the frequency being currently received and continues in the ascending order of the frequency. When all frequencies are searched through, if six or more stations are not detected, the search switches to DX mode and continues in it. If six or more stations are detected in local mode, or all frequencies are searched through in DX mode, the auto-storage operations ends. Pressing the P. SCAN key in local mode switches to DX mode, and restarts the search operation at the frequency selected when the previous search began. Any stations detected in local mode are made ineffective. (Stations detected in local mode are excluded during preset memory updating.) Pressing the P. SCAN key in DX mode ends the auto-storage operation, and causes the frequency selected when the auto-storage operation began to be received. If six or more stations are detected in local mode, or all frequencies are searched through in DX mode, the auto-storage operation ends. If at least one station is detected, the contents of the preset memories are updated, and the preset scan begins with the M1 preset memory. How the contents of the preset memories are updated varies depending on the number of stations detected, as follows: If six or more stations are detected in local mode: If six or more stations are detected in local mode, six stations with a higher SD input are selected and written to the preset memories, with a lower frequency written to a lower-numbered preset memory. If less than six stations are detected in local mode, and some are detected in DX mode, resulting in a total of six or more stations being detected: Stations detected in DX mode with higher SD input levels are selected and added to the number of stations detected in local mode so that the total becomes six. In this case, the stations detected in local mode are excluded from those detected in DX mode. The frequencies of the six stations are written to the preset memories, with a lower frequency written to a lower-numbered preset memory. If less than six stations are detected in local mode and some are detected in DX mode, resulting in a total of less than six stations being detected: If the same station is detected in DX and local modes, the station detected in DX mode is deleted so that the same frequency will not be written to two preset memories. The frequencies of the less than six stations detected are written to the preset memories, with a lower frequency written to a lower-numbered preset memory. The contents of a preset memory will not be changed if there is no frequency corresponding to it.

Momentary key RDMONI Description The RDMONI key controls radio monitoring. It is effective in tape, CD, radio-monitor tape, or radiomonitor CD mode. Each time the key is pressed, radio monitor mode is set or reset. In radio monitor mode, the "RDMONI" display on the LCD panel lights. In radio monitor mode, tuning is enabled for all bands, the radio mute function (RDMUTE pin) is switched off, and the audio mute function (AMUTE pin) is switched on. Radio monitor mode is reset by: Change in the TPSET switch state Change in the CDSET switch state Change at the CE pin from high level to low levelNote Note When using alarm mode, always pull up the CE pin. SCAN UP SCAN DWN The SCAN UP and SCAN DWN keys are used for auto-tuning (scan operation). Pressing the SCAN UP key ( SCAN DWN key) increases (decreases) the frequency by one channel space and checks whether there is a broadcasting station at each reception frequency (frequency counter and SD signal). If a broadcasting station is detected, the corresponding frequency is held for five seconds. If no key is pressed within this hold time of five seconds, the seek operation restarts. If another broadcasting station is detected, the corresponding frequency is held in the frequency counter for five seconds. This operation is repeated (scan operation) sequentially. The frequency display blinks at 1 Hz (with a duty cycle of 50%) during the five-second hold time. A beep occurs at the end of the hold time. The seek operation here is the same as one performed with the SEEK UP key. The following table lists the operation corresponding to each key pressed during the seek operation (except the hold time). Key SCAN UP SCAN DWN Description If the SCAN UP key is pressed in scan-up mode, or the SCAN DWN key is pressed in scan-down mode: The scan operation stops, and the frequency that was selected when the scan operation began is reselected. If the auto local function is being used, local mode is switched. If the SCAN DWN key is pressed in scan-up mode, or the SCAN UP key is pressed in scan-down mode: The operation corresponding to the pressed key begins at the frequency that is selected when the key is pressed. The scan operation stops, and the operation corresponding to the pressed key begins at the frequency that is selected when the key is pressed.

Momentary key SEEK UP Description The SEEK UP key is used for auto-tuning (seek operation). Pressing the SEEK UP key increases the frequency by one channel space and checks whether there is a broadcasting station at each reception frequency (by a method determined depending on the states of the ENAMIF and ENFMIF initial setting diodes). If a broadcasting station is detected, the seek operation ends. The seek operation performed varies with the state of the AUTOLOC initial setting diode as follows: (1) When AUTOLOC = 0 (with no auto local function): A search operation begins at the frequency currently being received. The search operation continues in local or DX mode whichever has been selected when the search operation starts, until a station is detected. (2) When AUTOLOC = 1 (with an auto local function): A search operation begins at the frequency being currently received in local mode. When all frequencies are searched through in local mode, a search operation is switched to DX mode and continues until a station is detected. If the SEEK UP key is pressed in local mode, DX mode is selected, and a search operation restarts with the same frequency as for the previous search. If the SEEK UP key is pressed during a search in DX mode, the search operation ends, and the frequency at which the search operation began is selected. When using the SEEK UP key, set the AUTO500 initial setting diode to 0. Setting it to 1 disables the SEEK UP key. The SEEK UP key functions during the search operation as follows:

VOL DWN
The VOL DWN key is used to adjust the volume of sound in each electronic volume control mode. The operation depends on the state of the VKYSEL initial setting diode. VKYSEL 0 Description Pressing the VOL DWN key in a mode other than an electronic volume control mode selects volume mode and increases the volume of sound. In an electronic volume control mode selected by the VOL SEL key, pressing the VOL DWN key activates the operation corresponding to the selected mode as follows: Mode Volume Bass Treble Balance Fader Function Decreases the main sound volume. Decreases the bass. Decreases the treble. Emphasizes the sound volume from the left-side speaker. Emphasizes the sound volume from the rear speaker.
Keeping the VOL DWN key pressed for at least 0.5 seconds controls the volume continuously. If no key is pressed for at least 3 seconds, the mode previous to the current electronic volume control mode is reselected. 1 The VOL DWN key is ineffective. After an electronic volume control mode is selected using the VOL SEL key, the MAN DWN key can be used to perform the same adjustment that would be performed using the VOL DWN key. Pressing the MAN DWN key in a mode other than an electronic volume control mode does not select volume mode. See the descriptions of the MAN UP and MAN DWN keys for details.

Momentary key VOL UP Description The VOL UP key is used to adjust the volume of sound in each electronic volume control mode. The operation depends on the state of the VKYSEL initial setting diode. VKYSEL 0 Description Pressing the VOL UP key in a mode other than an electronic volume control mode selects volume mode and increases the volume of sound. In an electronic volume control mode selected by the VOL SEL key, pressing the VOL UP key activates the operation corresponding to the selected mode as follows: Mode Volume Bass Treble Balance Fader Function Increases the main sound volume. Increases the bass. Increases the treble. Emphasizes the sound volume from the right-side speaker. Emphasizes the sound volume from the front speaker.
Keeping the VOL UP key pressed for at least 0.5 seconds controls the volume continuously. If no key is pressed for at least 3 seconds, the mode previous to the current electronic volume control mode is reselected. 1 The VOL UP key is ineffective. After an electronic volume control mode is selected using the VOL SEL key, the MAN UP key can be used to perform the same adjustment that would be performed using the VOL UP key. Pressing the MAN UP key in a mode other than an electronic volume control mode does not select volume mode. See the descriptions of the MAN UP and MAN DWN keys for details.

4. MODE TRANSITION The radio set is turned on or off by switching the RDSET switch. The RDSET, TPSET, and CDSET switches are enabled only when the CE and IGNITION pins are high. When the IGNITION pin is made low, clock display is not provided regardless of state of the initial setting diode NOCLK. However, when NOCLK = 0 (for using the clock), the clock operates. Transition to alarm mode is possible when the IGNITION pin is at a low level. The CE pin must be fixed to a high level. (1) Mode transition when the IGNITION pin is raised from low to high The RDSET switch is used to turn on or off radio mode. The TPSET and CDSET switches are used to switch to tape mode and CD mode.

APPENDIX COMMUNICATION WITH ELECTRONIC VOLUME CONTROL IC (I2C BUS INTERFACE)
The PD17012-058 sends specified data, such as volume and balance data, to the electronic volume control IC. Two buses, the data bus and clock bus, are necessary to output data to the electronic volume control IC. Data and clock signals are output from the EVOL_DA pin (pin 2) and EVOL_SCK pin (pin 1) of the PD17012-058. Figure A-1. Pin Connections (Electronic Volume Control)

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS device behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.

No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in this document. NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
