2.0
There are three memory blocks in each of the
PIC16F87XA devices. The program memory and data
memory have separate buses so that concurrent
access can occur and is detailed in this section. The
EEPROM data memory block is detailed in Section 3.0
“Data EEPROM and Flash Program Memory”.
Additional information on device memory may be found
in the PICmicro
Manual (DS33023).

2.1
The PIC16F87XA devices have a 13-bit program
counter capable of addressing an 8K word x 14 bit
program memory space. The PIC16F876A/877A
devices have 8K words x 14 bits of Flash program
memory,
4K words x 14 bits. Accessing a location above the
physically
wraparound.
The Reset vector is at 0000h and the interrupt vector is
at 0004h.
