3.0
3.1
The PIC16C432 has a 13-bit program counter capable
of addressing an 8K x 14 program memory space. Only
the first 2K x 14 (0000h - 07FFh) are implemented for
the PIC16C432. Accessing a location above these
boundaries will cause a wrap-around within the first 2K
x 14 space. The RESET Vector is at 0000h and the
Interrupt Vector is at 0004h (Figure 3-1).

3.2
The data memory (Figure 3-2) is partitioned into two
Banks, which contain the General Purpose Registers
and the Special Function Registers. Bank 0 is selected
when the RP0 bit is cleared. Bank 1 is selected when
the RP0 bit (STATUS <5>) is set. The Special Function
Registers are located in the first 32 locations of each
Bank. Register locations 20-7Fh (Bank 0) and A0-BFh
(Bank 1) are General Purpose Registers implemented
as static RAM. Some special purpose registers are
mapped in Bank 1. In the microcontroller, address
space F0h-FFh (Bank 1) is mapped to 70-7Fh (Bank 0)
as common RAM.
3.2.1
The register file is organized as 128 x 8 in the
PIC16C432. Each is accessed either directly or indi-
rectly
(Section 3.4).
