Data Memory Organization
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 PIC16C505, the register file is composed of 8
special function registers, 24 general purpose
registers, and 48 general purpose registers that may
be addressed using a banking scheme (Figure 4-2).
4.2.1
GENERAL PURPOSE REGISTER FILE
The general purpose register file is accessed either
directly or indirectly through the file select register
FSR (Section 4.8).
