The program memory stores a program, interrupt vector table, and fixed data table.

The program memory is addressed by the program counter.

Figure 2-4 shows the program memory map. The entire range of the program memory can be addressed by the

BD addr, BR @AR, CALL @AR, MOVT DBF, and @AR instructions. Note, however, that the subroutine entry

addresses that can be specified by the CALL addr instruction are from 0000H to 07FFH.
