4.2
Data memory is composed of registers, or bytes of
RAM. Therefore, data memory for a device is specified
by its register file. The register file is divided into two
functional groups: special function registers and
general purpose registers.
The special function registers include the TMR0
register, the Program Counter (PC), the Status
Register, the I/O registers (ports), and the File Select
Register (FSR). In addition, special purpose registers
are used to control the I/O port configuration and
prescaler options.
The general purpose registers are used for data and
control information under command of the instructions.
For the PIC12C508, PIC12C508A and PIC12CE518,
the register file is composed of 7 special function
registers and 25 general purpose registers (Figure 4-
2).
For the PIC12C509, PIC12C509A, PIC12CR509A,
and PIC12CE519 the register file is composed of 7
special
registers, and 16 general purpose registers that may
be addressed using a banking scheme (Figure 4-3).
4.2.1
The general purpose register file is accessed either
directly or indirectly through the file select register FSR
(Section 4.8).
