(1) standby operation the acc and batt pins are tested every 2 ms five times to suppress chattering. after chattering has been suppressed, the mode is changed from the normal operation mode to the standby mode when the acc or batt pin goes high. if the acc or batt pin is high since power application, the standby mode is selected on completion of chattering suppression. in the standby mode, none of the functions, except ejecting the disc, can be used. in addition, the lcd panel displays nothing. the clock is not displayed in the standby mode even if the clock function is specified by using the initialization switch noclk. internally, however, the clock count continues in the same manner as in the normal operation mode. in the standby mode, the m pd178024gc-051 performs an intermittent operation by oscillating and stopping the cpu clock to reduce its own current consumption. if the clock function is not specified, oscillation of the cpu clock and system clock is completely stopped in the standby mode. consequently, the current consumption of the m pd178024gc-051 is substantially reduced. in the standby mode, each pin is placed in the status that lowers the current consumption. for the pin statuses at this time, refer to 1. pin functions. (2) operation after releasing standby mode if the internal falling edge detector of the m pd178024gc-051 detects negative transition of the acc pin (pin 69) or batt pin (pin 70), the standby mode is temporarily released, and the acc and batt pins are tested. if both the acc and batt pins are high, the standby mode is immediately resumed. if either of the pins is low, the standby mode is released, and the normal operation mode is set. when the standby mode has been released, the previous power status and audio source mode selected before the standby mode was set are restored. similarly, the reception frequency of the radio, the contents of the preset memories, the volume values of the electronic volume, and other functions are restored to the status before the standby mode was set. if the contents of the internal memory could not be retained because the supply voltage dropped and if the result of reading the initialization switches differs from before, all the statuses are returned to the default statuses in the same manner as on power application. (3) ejecting disc in standby mode if the internal falling edge detector of the m pd178024gc-051 detects the negative transition of the eject pin (pin 71), the standby mode is temporarily released and the disc is ejected in the normal mode. at this time, eject indication is not made on the display. as soon as the disc has been ejected, the standby mode is resumed.

(1) setting gain of electronic volume ic the gain of the electronic volume ic is set to 0 db. (2) adjusting volume the volume can be adjusted in each of the following modes: mode function adjustment range default value on power application volume adjusts volume of main volume. 00 to 63 28 bass adjusts volume of bass (low-frequency region). - 6 to +6 00 (no bass compensation) treble adjusts volume of treble (high-frequency region). - 6 to +6 00 (no treble compensation) balance adjusts volume balance between left and right. r31 to l31 00 (center position between left and right) fader adjusts volume balance between front and rear f31 to r31 00 (center position between front and rear) however, the fader cannot be adjusted if the fader adjustment function is not specified by the initialization switch fadsel. when equalize processing is performed by the electronic volume and when the equalizer mode is other than flat, bass and treble cannot be adjusted. for equalizer processing by the electronic volume, refer to (4) equalizer processing by electronic volume. to adjust the volume, select an adjustment mode by using the vol sel/vol clr key, and make an adjustment by using the vol up and vol dwn keys. for the specific adjustment method, refer to the description of each of the above keys. on power application, the volume value in each mode is set to the default value. on power application and on releasing the standby mode, the main volume value set at that time is returned to the default value if it is greater than the default value, or is retained if it is less than the default value. at this time, the volume values in the bass, treble, balance, and fader modes are retained regardless of their values. for the correspondence between the displayed volume values and the set values of the electronic volume ic, refer to 11.2 electronic volume ic (tda7313) set values.
data sheet u14608ej1v0ds00 76 m m m m pd178024gc-051 (3) loudness control each time the loud key is pressed, loudness is turned on or off. when loudness is on, the loud pin (pin 39) outputs a low level, and the loudness of the electronic volume ic is turned on. if the loudness of the electronic volume ic is on, the gain of the electronic volume ic is amplified by +7.5 db. (4) equalizer processing by electronic volume ic if it is specified by the initialization switch eqicsel that the equalizer is not used, equalizer processing by the electronic volume ic is performed. equalizer processing by electronic volume ic is performed by setting the gain of the bass and treble in an equalizer mode. at this time, the bass adjustment mode and treble adjustment mode are skipped when an electronic volume mode is selected by using the vol sel key in an equalizer mode other than flat. therefore, bass and treble cannot be adjusted. bass and treble are adjusted as follows in each equalizer mode. equalizer mode range gain bass adjustable by bass adjustment operation flat treble adjustable by treble adjustment operation bass fixed to +6 db (cannot be adjusted) rock treble fixed to +2 db (cannot be adjusted) bass fixed to +2 db (cannot be adjusted) classic treble fixed to +2 db (cannot be adjusted) bass fixed to - 4 db (cannot be adjusted) pop treble fixed to - 2 db (cannot be adjusted) (5) mute setting of electronic volume in the mute-on status, the mute pin outputs a low level, and the electronic volume ic is muted. for the mute value of the electronic volume ic, refer to 11.2 electronic volume ic (tda7313) set values.

data sheet u14608ej1v0ds00 95 m m m m pd178024gc-051 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 devices 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 v dd 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. purchase of nec i 2 c components conveys a license under the philips i 2 c patent rights to use these components in an i 2 c system, provi ded that the system conforms to the i 2 c standard specification as defined by philips.
