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.
