4.1
The PIC14000 has a 13-bit program counter capable of
addressing an 8K x 14 program memory space. Only
the first 4K x 14 (0000-0FFFh) are physically imple-
mented. 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 (Figure 4-1).
The 4096 words of Program Memory space are divided
into:
• Address Vectors (addr 0000h-0004h)
• Program Memory Page 0 (addr 0005h-07FFH)
• Program Memory Page 1 (addr 0800h-0FBFh)
• Calibration Space (64 words, addr 0FC0h-0FFFh)
Program code may reside in Page 0 and Page 1.

The calibration space is not used for instructions. This
section stores constants and factors for the arithmetic
calculations to calibrate the analog measurements.
