Each block (Program Memory and Data Memory) has its own bus, so that concurrent access can occur. Additional information on device memory may be found in the PICmicro ™ Mid-Range Reference Manual, (DS33023). 2.1 Program Memory Organization The PIC16C62B/72A devices have a 13-bit program counter capable of addressing an 8K x 14 program memory space. Each device has 2K x 14 words of pro- gram memory. Accessing a location above 07FFh will cause a wraparound. The reset vector is at 0000h and the interrupt vector is at 0004h.
