2.2
The data memory is partitioned into multiple banks,
which contain the General Purpose Registers (GPRs)
and the Special Function Registers (SFRs). Bits RP0
and RP1 are bank select bits.

Each bank extends up to 7Fh (128 bytes). The lower
locations of each bank are reserved for the Special
Function Registers. Above the Special Function
Registers are the General Purpose Registers,
implemented as static RAM. All implemented banks
contain Special Function Registers. Some frequently
used Special Function Registers from one bank are
mirrored in another bank for code reduction and
quicker access.
2.2.1
The register file is organized as 256 x 8 in the
PIC16F913/914 and 352 x 8 in the PIC16F916/917.
Each register is accessed either directly or indirectly
through the File Select Register (FSR) (see Section 2.5
“Indirect Addressing, INDF and FSR Registers”).
2.2.2
The Special Function Registers are registers used by
the CPU and peripheral functions for controlling the
desired operation of the device (see Tables 2-1,
The special registers can be classified into two sets:
core and peripheral. The Special Function Registers
associated with the “core” are described in this section.
Those related to the operation of the peripheral
features are described in the section of that peripheral
feature.
