2.3 Accessible area

Figure 2.3.1 shows the M37733MHBXXXFP’s accessible area.

Although the program counter (PC) consists of 16 bits, it can access the 16-Mbyte area at addresses 016

to FFFFFF16, combined with the program bank register (PG). For details about access to the external, refer

to chapter “12. CONNECTING EXTERNAL DEVICES.”

The memories and I/O units are allocated in the same accessible area. Therefore, operations such as data

transfer, arithmetic, and others can be performed with the same instructions. (It is not necessary to distinguish

the memories and I/O units.)

• SFR : Special Function Register

represents the memory allocation of internal

areas.

indicates that nothing is allocated.

Note: Memory allocation of the internal area in bank 016 depends on the microcomputer’s type and

settings of the memory allocation selection bits.

The above diagram shows the M37733MHBXXXFP’s accessible area immediately after reset.

For the other microcomputers of the 7733 Group, refer to section “Appendix 1. Memory

allocation of 7733 Group.” For settings of the memory allocation selection bits, refer to section

“2.4 Memory allocation .”
