2.0
There are two memory blocks in each of these micro-
controllers. 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
(DS33023).
2.1
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.
