2.0
There are two memory blocks in each of these
PICmicro
data memory) has its own bus, so that concurrent
access can occur.
Additional information on device memory may be found
in the PICmicro™ Mid-Range Reference Manual,
(DS33023).
2.1
The PIC16C781/782 devices have a 13-bit program
counter capable of addressing an 8K x 14 program
memory space. The PIC16C781 has 1K x 14 words of
program memory. The PIC16C782 has 2K x 14 words
of program memory. Accessing a location above the
physically implemented address causes a wraparound.
The RESET vector is at 0000h and the interrupt vector
is at 0004h.

The data memory is partitioned into multiple banks,
which contain the General Purpose Registers and the
Special Function Registers. Bits RP0 and RP1 are
bank select bits.

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 the General Purpose Registers, implemented
as static RAM. All implemented banks contain Special
Function Registers. Some frequently used Special
Function Registers from one bank are mirrored in
another bank for code reduction and quicker access.
