1.General Description
This OTP-Based 8-bit micro-controller uses a fully static CMOS technology process to achieve higher speed and smaller chip size with the 3K low power of consumption and high noise immunity. On memory includes words EPROM, and 128bytes of static RAM. while PED is Disable Power Edge-detector Reset (PED) Interrupt capability Timer0:8-bit timer with 8-bit prescaler (RTCC) Timer1:16bit timer with 16bit compare register. This timer can be used as carrier generator. 4 Channel comparator Sleep mode for power saving. PB with port change wake- up interrupt
2.Features
RISC CPU Fully static design 37 single word instructions 3K 14 program memory 128 bytes RAM for data 23 bi-directional I/O Eight level hardware stacks Watchdog timer (WDT) with on-chip RC oscillator Power-On Reset (POR) ,only available
3.Applications
The application areas of this NEW MCU range from appliance motor control and high speed automotive to low power remote transmitters/receivers and telecommunications processors, such as Remote controller, small instruments, toy , automobile and keyboard...etc.

TIMER1 timer/counter
Timer1 is a 16bit timer/counter consisting two 8-bit register (TMR1H and TMR1L) increment from 0000h to FFFFh.Timer1 can operate two mode (time mode and counter mode).Used the TICON register to control Timer1 mode Timer1 ccp mode: timer1 can internal "reset " by CCP mode,CCP register consisting two 8bit register ccp1L and ccp1H and control the register(17H-bit0) enable the comparator to reset timer1
