MEMORY ORGANIZATION
4.1
Program Memory Organization
The PIC16C55X has a 13-bit program counter capable
of addressing an 8 K x 14 program memory space.
Only the first 512 x 14 (0000h - 01FFh) for the
PIC16C554 and 2K x 14 (0000h - 07FFh) for the
PIC16C557 and PIC16C558 are physically imple-
mented. Accessing a location above these boundaries
will cause a wrap-around within the first 512 x 14
spaces in the PIC16C554, or 2K x 14 space of the
PIC16C558 and PIC16C557. The RESET vector is at
0000h and the interrupt vector is at 0004h (Figure 4-1,

4.2
Data Memory Organization
The data memory (Figure 4-3 through Figure 4-5) is
partitioned into two banks which contain the General
Purpose Registers (GPR) and the Special Function
Registers (SFR). Bank 0 is selected when the RP0 bit
(STATUS <5>) is cleared. Bank 1 is selected when the
RP0 bit is set. The Special Function Registers are
located in the first 32 locations of each Bank. Register
locations 20-6Fh (Bank 0) on the PIC16C554 and 20-
7Fh (Bank 0) and A0-BFh (Bank 1) on the PIC16C558
and PIC16C557 are General Purpose Registers imple-
mented as static RAM. Some special purpose registers
are mapped in Bank 1.
4.2.1
GENERAL PURPOSE REGISTER
FILE
The register file is organized as 80 x 8 in the
PIC16C554 and 128 x 8 in the PIC16C557 and
PIC16C558. Each can be accessed either directly or
indirectly through the File Select Register, FSR
