MCU MODULE DISCRIPTION
This section provides a detail description of the
MCU Module system functions and Peripherals,
including:

– Timers/Counter
– Interrupts
– PWM
– Supervisory Function (LVD and Watchdog)
– USART
– Power Saving Modes
– I
2
C Bus
– On-chip Oscillator
– ADC
– I/O Ports
– USB
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.

Note: 1. Register can be bit addressing
