PIC16LF1902/3
3.2.2
The Special Function Registers (SFRs) 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
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.
