4.0
4.1
The PIC16C63A/65B/73B/74B has a 13-bit program
counter capable of addressing an 8K x 14 program
memory space. All devices covered by this data sheet
have 4K x 14 bits of program memory. The address
range is 0000h - 0FFFh for all devices.
Accessing a location above 0FFFh will cause a wrap-
around.
The RESET vector is at 0000h and the interrupt vector
is at 0004h.

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.
RP1:RP0 (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. Frequently used
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).
