PIC16LF1904/6/7
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 Special Function
Registers occupy the 20 bytes after the core registers of
every data memory bank (addresses x0Ch/x8Ch
through x1Fh/x9Fh). The registers associated 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. The Special Function Registers occupy the 20
bytes after the core registers of every data memory
bank (addresses x0Ch/x8Ch through x1Fh/x9Fh).
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.
