Special Function Registers (SFRs)
Most interrupt and module enable bits are collected into the lowest address space. Special function register bits
not allocated to a functional purpose are not physically present in the device. Simple software access is provided
with this arrangement.
Legend
rw:
Bit can be read and written.
rw-0,1:
Bit can be read and written. It is reset or set by PUC.
rw-(0,1):
Bit can be read and written. It is reset or set by POR.
SFR bit is not present in device.
