4.0
4.1
The PIC16C745/765 has a 13-bit program counter
capable of addressing an 8K x 14 program memory
space. All devices covered by this data sheet have 8K
x 14 bits of program memory. The address range is
0000h - 1FFFh for all devices.
The reset vector is at 0000h and the interrupt vector is
at 0004h.

Preliminary
4.2
The data memory is partitioned into multiple banks
which contain the General Purpose Registers (GPR)
and the Special Function Registers (SFR). Bits RP1
and RP0 are the bank select bits.
RP<1:0> (STATUS<6:5>)
Each bank extends up to 7Fh (128 bytes). The lower
locations of each bank are reserved for the SFRs.
Above the SFRs are GPRs, implemented as static
RAM.
All implemented banks contain SFRs. Some “high use”
SFRs from one bank may be mirrored in another bank
for code reduction and quicker access.
4.2.1
The register file can be accessed either directly or indi-
rectly through the File Select Register (FSR)
(Section 4.5).
