5. FUNCTION DESCRIPTIONS 5.1 Oscillator
System clock define 2 Mhz, the souce provided by internal R-type ring oscillator or external resistor ring oscillator. This option is controlled by pin, RCSEL. RCSEL = 1 using the external R 180Kohm RCSEL = 0 using the internal R
5.2
ROM
SNC21060 contains a substantial maximum 184K words (10-bit) internal ROM, which is shared by program and resource data. Program, voice and data are shared within this same 184K words ROM.
5.3
RAM
SNC21060 contains maximum 128 nibble RAM (128 x 4-bits). The 128 nibble RAM is divided into eight pages (page 0 to page 7, 16 nibble RAM on each page). In our programming structure, users can use the instructions, PAGE n (n=0 to 7) to switch and indicate the RAM page. Besides, users can use direct mode, M0 ~ M15 in the data transfer type instructions, to access all 16 nibbles of each page.
5.4
Power Down Mode
"End" instruction makes the IC entering into Stop Mode will stop the system clock for power savings (<3uA @VDD=3V and <6uA @VDD=4.5V.) Any valid data transition (L H or H L) occurring on any IO pin can be used to start the system clock and return to normal operating mode.
5.5
Sampling Rate Counter
The unique sampling rate counter is designed in voice channel to be able to play diverse voices at different sample playing rates. The playing rate can be adaptively set up among from the wide ranges of 2.5KHz to 20KHz. This architecture yields a high-quality voice synthesis that sounds very close to its original source when played through the same amplifier and speaker circuitry.

5.6
I/O Ports
There are three 4-bit I/O ports P1, P2 and P3. Any I/O can be individually programmed as either input pull low or output. Any valid data transition (H L or L H) of P1, P2 and P3 can reactivate the chip when it is in power-down stage.

Read Control
I/O Port Configuration Note: (1) Weak N-MOS can serve as pull-low resistor. (2) The driving/sink current of P3.3 & P3.2 is up to 8mA/16mA
5.7
IR Function
Bit 3 of Mode Register is applied to control the IR function. P33 can be modulated with 38.5KHz square wave before sent out to P3.3 or P2.3 pin. P3.3 and P2.3 out is controlled by Mode1.1. If Mode1.1 set 1 IR is use P2.3, set "0" is use P3.3. The IR signal can be achieved by this modulated signal.
5.8
PWM IO control
SNC21060 have support 4 PWM IO (P30~P33). Each I/O has 8 bits independent duty register.
5.9
Watch Dog Timer
SNC21060 built an internal WDT (Watch Dog Timer). This Watchdog timer would issue resets signal to this chip if it is not cleared before reaching terminal count (1sec). The watchdog timer is enabled at reset and cannot be disabled.

Push-Pull Output
An 8-level volume control Push-Pull Direct Drive circuit is built-in SNC21060. The maximum resolution of Push-Pull is 12 bits. Two huge output stage circuits are designed in SNC21060. With this advanced circuit, the chip is capable of driving speaker directly without external transistors.

Mark register
If user had insert Mark into wave file. The Mark data will be fetched into this register during voice playing. The content of this register will be cleared to "0" automatically once user accesses this register.
5.12
Low Voltage Hold
This function enables chips entering Hold mode when voltage is below 2.1V and will back to work after voltage rise up to 2.1V. Chip will not entering hold mode before current Instruction finish. When chip in Hold mod, ROSC will keep running, and all the content of Latch/Register/SRAM will keep unchanged.
