MEMORY ORGANIZATION
There are two memory blocks in the PIC16F84A.
These are the program memory and the data memory.
Each block has its own bus, so that access to each
block can occur during the same oscillator cycle.
The data memory can further be broken down into the
general purpose RAM and the Special Function
Registers (SFRs). The operation of the SFRs that
control the “core” are described here. The SFRs used
to control the peripheral modules are described in the
section discussing each individual peripheral module.
The data memory area also contains the data
EEPROM memory. This memory is not directly mapped
into the data memory, but is indirectly mapped. That is,
an indirect address pointer specifies the address of the
data EEPROM memory to read/write. The 64 bytes of
data EEPROM memory have the address range
0h-3Fh. More details on the EEPROM memory can be
found in Section 3.0.
Additional information on device memory may be found
in the PICmicro Mid-Range Reference Manual,
(DS33023).

Program Memory Organization
The PIC16FXX has a 13-bit program counter capable
of addressing an 8K x 14 program memory space. For
the PIC16F84A, the first 1K x 14 (0000h-03FFh) are
physically implemented (Figure 2-1). Accessing a loca-
tion above the physically implemented address will
cause a wraparound. For example, for locations 20h,
420h, 820h, C20h, 1020h, 1420h, 1820h, and 1C20h,
the instruction will be the same.
The RESET vector is at 0000h and the interrupt vector
is at 0004h.
