MCU MODULE DISCRIPTION

This section provides a detail description of the

MCU Module system functions and Peripherals,

including:

■ Special Function Registers

■ Timers/Counter

■ Interrupts

■ PWM

■ Supervisory Function (LVD and Watchdog)

■ USART

■ Power Saving Modes

■ I2C Bus

■ On-chip Oscillator

■ ADC

■ I/O Ports

Special Function Registers

A map of the on-chip memory area called the Spe-

cial Function Register (SFR) space is shown in Ta-

ble 15.

Note: In the SFRs not all of the addresses are oc-

cupied. Unoccupied addresses are not implement-

ed on the chip. READ accesses to these

addresses will in general return random data, and

WRITE accesses will have no effect. User soft-

ware should write '0s' to these unimplemented lo-

cations.
