2.3 Accessible area

Concerning section “2.3 Accessible area,” the 7735 Group differs from the 7733 Group in the following:

• Accessible area which is allocated to addresses 016 to 0FFFFF16 (Maximum of 1 Mbytes)

• Figure 2.3.1

The other description is the same as that of the 7733 Group. Therefore, refer to part 1:

• “2.3 Accessible area” (page 2–16 in part 1)

Notes 1: Banks 1016 to FF16 cannot be accessed.

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

settings of the memory allocation selection bits.

The above diagram shows the M37735MHBXXXFP’s accessible area immediately after reset.

For the other microcomputers of the 7735 Group, refer to “Appendix 1. Memory allocation of

7735 Group.” For settings of the memory allocation selection bits, refer to section “2.4 Memory

allocation.”
