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

Note:

Special function registers

A map of the on-chip memory area called the Special Function Register (SFR) space is

shown in Table 15.

In the SFRs not all of the addresses are occupied. Unoccupied addresses are not

implemented on the chip. READ accesses to these addresses will in general return random

data, and WRITE accesses will have no effect. User software should write '0s' to these

unimplemented locations.
