2.1 Program Counter (PC)
The program counter (PC) specifies an address of the program memory (ROM).
The program counter is a 11/12/13-bit binary counter as shown in Fig. 2-1.
Its contents are initialized to address 0000H at reset.

2.2 Program Memory (ROM)
The configuration of the program memory is as follows:
Part Number

2048 x 16 bits
0000H-07FFH

6144 x 16 bits
0000H-17FFH
μ
PD17218
8192 x 16 bits
0000H-1FFFH
The program memory stores a program, interrupt vector table, and fixed data table.
The program memory is addressed by the program counter.
Fig. 2-2 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.
