ROM TABLE The total ROM size is 1024K words. It split two parts including high speed and low speed ROM area, but user also can program all area. In high speed ROM had a small OS to control all function flow. We recommend user put you program in high speed ROM and put data in low speed ROM to get high performance. 0x000000 High Speed ROM (64K W ords) 0x00FFFF 0x010000 0xFFFFFF Ver. 1.5 ~ Total ROM Size 1024K Words Low Speed ROM (960K W ords) 6 March 7, 2007 Preliminary SNC759 16-bit Voice Processor 5.

System Clock The system clock had dual source high clock and low clock input, user can selected from 16Mhz crystal or ROSC for high clock and 32768 crystal for low clock. In Normal mode, user can select high clock source from 16Mhz crystal or ROSC, In Slow mode, user must select 32768 crystal to input system clock. 6.1 Crystal Input GND CKSEL High Clock Low Clock 6.2 ROSC Input User uses ROSC mode to make High clock. The internal clock is reference clock from 32768 X’tal to fine tune to 16MHz. So, when ROSC mode is select, the 32768 X’tal must provide reference clock to system.

I/O PORT SNC759 provides one a 24-bit I/O port for user application (P0.0~P0.15, P1.0~P1.7). The input pull high resistor of each pin can be programmed by Port Pull-High register. The direction of I/O port is selected by Port Direction register. The Port0 (P0.0~P0.15) and Port1 (P1.0~P1.7) can wake the chip up from the stop mode and watch mode. P0.15 can be modulated with a 38.5Khz carry signal to realize IR signal transmission. When user uses GPIO to wake up chip, the GPIO must setting to input mode and Pull-High all I/O pin.

TIMER/COUNTER SNC759 provides three 8-bit timer/event counters (T0/T1/T2). Each timer is 8-bit binary up-count timer with pre-scalar and auto-reload function. Timer 0 (T0) is used when voice playing, so user should avoid to use T0.
