4.0
MEMORY ORGANIZATION
4.1
Program Memory Organization
The PIC12CE67X has a 13-bit program counter capa-
ble of addressing an 8K x 14 program memory space.
For the PIC12CE673 the first 1K x 14 (0000h-03FFh) is
implemented.
For the PIC12CE674, the first 2K x 14 (0000h-07FFh)
is implemented. Accessing a location above the physi-
cally implemented address will cause a wraparound.
The reset vector is at 0000h and the interrupt vector is
at 0004h.

4.2
The data memory is partitioned into two Banks which
contain the General Purpose Registers and the Special
Function Registers. Bit RP0 is the bank select bit.
RP0 (STATUS<5>) = 1
→
Bank 1
RP0 (STATUS<5>) = 0
→
Bank 0
Each Bank extends up to 7Fh (128 bytes). The lower
locations of each Bank are reserved for the Special
Function Registers. Above the Special Function Regis-
ters are General Purpose Registers implemented as
static RAM. Both Bank 0 and Bank 1 contain special
function registers. Some "high use" special function
registers from Bank 0 are mirrored in Bank 1 for code
reduction and quicker access.
Also note that F0h through FFh on the PIC12CE67X is
mapped into Bank 0 registers 70h-7Fh.

GENERAL PURPOSE REGISTER FILE
The register file can be accessed either directly, or indi-
rectly through the File Select Register FSR
(Section 4.5).
