2.0
There are two memory blocks in each of these
PICmicro
gram Memory and Data Memory) has its own bus
so that concurrent access can occur.
Additional information on device memory may be found
in the PICmicro
(DS33023).
2.1
The PIC16C77X PICmicros have a 13-bit program
counter capable of addressing an 8K x 14 program
memory space. Each device has 4K x 14 words of pro-
gram memory. 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.

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 “high use” special function
registers from one bank may be 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.
