FEATURES
1.	ROM: 4K x 16 bits Flash Program Memory
2.	EEPROM: 128 x 8 bits
3.	RAM: 336 x 8 bits
4.	STACK: 8 Levels
5.	System Clock type selections:
	Fast clock from 1~20 MHz Crystal (FXT)
	Fast clock from Internal RC (FIRC, 16 MHz)
	Slow clock from 32768 Hz Crystal (SXT)
	Slow clock from Internal RC (SIRC, 85 KHz@VCC=5V)
6.	System Clock Prescaler:
	System Clock can be divided by 1/2/4/8 option
7.	Power Saving Operation Mode
	FAST Mode: Slow-clock is enabled, Fast-clock keeps CPU running
	SLOW Mode: Fast-clock can be disabled or enabled, Slow-clock keeps CPU running
	IDLE Mode: Fast-clock and CPU stop. Slow-clock, T2, or Wake-up Timer keep running
	STOP Mode: All clocks stop, T2 and Wake-up Timer stop
8.	3 Independent Timers
	Timer0
-	8-bit timer divided by 1~256 pre-scale option / auto-reload / counter / interrupt / stop function
	Timer1
-	8-bit timer divided by 1~256 pre-scale option / auto-reload / interrupt / stop function
-	Overflow and Toggle out
	T2
-	15-bit timer with 4 interrupt interval time options
-	IDLE mode wake-up timer or used as one simple 15-bit time base
-	Clock source: Slow-clock, Fsys/128, or FIRC/512 (16 MHz/512)
 
9.	Interrupt
