2.0
There are two memory blocks in each of these
PICmicro
memory have separate buses so that concurrent
access can occur and is detailed in this section. The
program memory can be read internally by user code
(see Section 3.0 “Reading Program Memory”).
Additional information on device memory may be found
in the “PICmicro
Manual” (DS33023).
2.1
The PIC16F7X7 devices have a 13-bit program counter
capable of addressing an 8K word x 14-bit program
memory space. The PIC16F767/777 devices have
8K words of Flash program memory and the
PIC16F737/747 devices have 4K words. The program
memory maps for PIC16F7X7 devices are shown in
Figure 2-1. Accessing a location above the physically
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 (Status<6>) and
RP0 (Status<5>) 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
Function Registers from one bank may be mirrored in
another bank for code reduction and quicker access.
2.2.1
The register file (shown in Figure 2-2 and Figure 2-3)
can be accessed either directly, or indirectly, through
the File Select Register (FSR).
Memory available on PIC16F767
and PIC16F777. The memory
wraps to 000h through 0FFFh on
the PIC16F737 and PIC16F747.
Memory available on all
PIC16F7X7.
