SPECIAL FUNCTION REGISTER
The Special Function Registers (SFR) are registers
used by the application to control the desired operation
of peripheral functions in the device. The registers
associated with the operation of the peripherals are
described in the appropriate peripheral chapter of this
data sheet.

GENERAL PURPOSE RAM
There are up to 80 bytes of GPR in each data memory
bank.
bank.
3.2.3.1
Linear Access to GPR
The general purpose RAM can be accessed in a
non-banked method via the FSRs. This can simplify
access to large memory structures. See
