3.2.2
The Special Function Registers are registers used by
the application to control the desired operation of
peripheral functions in the device. The registers asso-
ciated with the operation of the peripherals are
described in the appropriate peripheral chapter of this
data sheet.
3.2.3
There are up to 80 bytes of GPR in each data memory
bank.
3.2.3.1
The general purpose RAM can be accessed in a
non-banked method via the FSRs. This can simplify
access to large memory structures. See
“Linear Data Memory”
3.2.4
There are 16 bytes of common RAM accessible from all
banks.
