2.2
The data memory is partitioned in up to 32 memory
banks with up to 128 bytes in a bank. Each bank
consists of 12 core registers, 20 Special Function
Registers (SFR), 16 common registers, and up to 80
bytes of General Purpose Registers (GPR). The active
bank is selected by writing the bank number into the
Bank Select Register (BSR). Unimplemented memory
will read as ‘0’. All banks contain the core SFRs and
common registers. Unimplemented SFRs or GPRs 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 (FSR). See
Section 2.5 “Indirect Addressing, INDF and FSR
Registers” for more information.
2.2.1
The general purpose register file is an 8-bit RAM
memory for use by your application. There are up to
80 bytes of GPR in each data memory bank.
2.2.2
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 can be classified into two sets: core and
peripheral. The Special Function Registers associated
with the “core” are described in the following sections.
The registers associated with the operation of the
peripherals are described in the appropriate peripheral
chapter of this data sheet.
