× 16 bits
0000H to 1FFFH
PD17244
10,240
× 16 bits
0000H to 27FFH
PD17245
12,288
× 16 bits
0000H to 2FFFH
PD17246

0000H to 3FFFH
The program memory stores the 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.
