• Direct, indirect addressing modes for data accessing
• 8-bit real time clock/counter (Timer0) with 8-bit programmable prescaler
• Internal Power-on Reset (POR)
• Built-in Low Voltage Detector (LVD) for Brown-out Reset (BOR)
• Power-up Reset Timer (PWRT) and Oscillator Start-up Timer(OST)
• On chip Watchdog Timer (WDT) with internal oscillator for reliable operation and soft-ware watch-dog
enable/disable control
• Two I/O ports IOA and IOB with independent direction control
• Soft-ware I/O pull-high/pull-down or open-drain control
• One internal interrupt source: Timer0 overflow; Two external interrupt source: INT pin, Port B input change
• Wake-up from SLEEP by INT pin or Port B input change
• Power saving SLEEP mode
• Programmable Code Protection
• Selectable oscillator options:
- RC: Resistor/Capacitor Oscillator
- XT: Crystal/Resonator Oscillator
- HF: High Frequency Crystal/Resonator Oscillator
- LF: Low Frequency Crystal Oscillator
• Wide-operating voltage range:
- EPROM : 2.3V to 5.5V
- ROM : 2.3V to 5.5V

1.2 Data Memory Organization
Data memory is composed of Special Function Registers and General Purpose Registers.
The General Purpose Registers are accessed either directly or indirectly through the FSR register.
The Special Function Registers are registers used by the CPU and peripheral functions to control the operation of
the device.
