2.0
There are two memory blocks in each of these PICmi-
cro
and Data Memory) has its own bus, so that concurrent
access can occur.
Additional information on device memory may be found
in the PICmicro
Manual, (DS33023).
2.1
The PIC16C717/770/771 devices have a 13-bit pro-
gram counter capable of addressing an 8K x 14 pro-
gram memory space. The PIC16C717 and the
PIC16C770 have 2K x 14 words of program memory.
The PIC16C771 has 4K x 14 words of program mem-
ory. Accessing a location above the physically imple-
mented address will cause a wrap-around.
The RESET vector is at 0000h and the interrupt vector
is at 0004h.

2.2
The data memory is partitioned into multiple banks,
which contain the General Purpose Registers and the
Special Function Registers. Bits RP1 and RP0 are the
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 General Purpose Registers, implemented as
static RAM. All implemented banks contain special
function registers. Some frequently used special func-
tion registers from one bank are mirrored in another
bank for code reduction and quicker access.
2.2.1
The register file can be accessed either directly, or indi-
rectly, through the File Select Register FSR.
