2.0
2.1
The PIC16F684 has a 13-bit program counter capable
of addressing an 8k x 14 program memory space. Only
the first 2k x 14 (0000h-07FFh) for the PIC16F684 is
physically implemented. Accessing a location above
these boundaries will cause a wrap around within the
first 2k x 14 space. The Reset vector is at 0000h and
the interrupt vector is at 0004h (see Figure 2-1).

2.2
The data memory (see Figure 2-2) is partitioned into two
banks, which contain the General Purpose Registers
(GPR) and the Special Function Registers (SFR). The
Special Function Registers are located in the first 32
locations of each bank. Register locations 20h-7Fh in
Bank 0 and A0h-BFh in Bank 1 are General Purpose
Registers, implemented as static RAM. Register
locations F0h-FFh in Bank 1 point to addresses 70h-7Fh
in Bank 0. All other RAM is unimplemented and returns
‘0’ when read. The RP0 bit of the STATUS register is the
bank select bit.

The IRP and RP1 bits of the STATUS
register are reserved and should always be
maintained as ‘0’s.
