2.1
The PIC12F629/675 devices have a 13-bit program
counter capable of addressing an 8K x 14 program
memory space. Only the first 1K x 14 (0000h-03FFh)
for the PIC12F629/675 devices is physically imple-
mented. Accessing a location above these boundaries
will cause a wrap-around within the first 1K x 14 space.
The Reset vector is at 0000h and the interrupt vector is
at 0004h (see Figure 2-1).

2.2
The data memory (see Figure 2-2) is partitioned into
two banks, which contain the General Purpose
Registers and the Special Function Registers. The
Special Function Registers are located in the first 32
locations of each bank. Register locations 20h-5Fh are
General Purpose Registers, implemented as static
RAM and are mapped across both banks. All other
RAM is unimplemented and returns ‘0’ when read. RP0
(STATUS<5>) is the bank select bit.
• RP0 = 0 Bank 0 is selected
• RP0 = 1 Bank 1 is selected
2.2.1
The register file is organized as 64 x 8 in the
PIC12F629/675 devices. Each register is accessed,
either directly or indirectly, through the File Select
Register FSR (see Section 2.4 “Indirect Addressing,
INDF and FSR Registers”).
Note:

The IRP and RP1 bits STATUS<7:6> are
reserved and should always be maintained
as ‘0’s.
