PIC16LF1902/3
3.2
The data memory is partitioned in 32 memory banks
with 128 bytes in a bank. Each bank consists of
(Figure
• 12 core registers
• 20 Special Function Registers (SFR)
• Up to 80 bytes of General Purpose RAM (GPR)
• 16 bytes of common RAM
The active bank is selected by writing the bank number
into the Bank Select Register (BSR). Unimplemented
memory will read as ‘0’. All data memory can be
accessed either directly (via instructions that use the
file registers) or indirectly via the two File Select
Registers
Addressing”
Data Memory uses a 12-bit address. The upper 7-bit of
the address define the Bank address and the lower
5-bits select the registers/RAM in that bank.

3.2.1
The core registers contain the registers that directly
affect the basic operation. The core registers occupy
the first 12 addresses of every data memory bank
(addresses x00h/x08h through x0Bh/x8Bh). These
registers are listed below in
information, see
