2.5 Processor modes

Concerning section “2.5 Processor modes,” the 7735 Group differs from that of the 7733 Group in the

following:

• “Fig. 2.5.1 Memory map in each processor mode”

• “Fig. 2.5.2 Pin configuration in each processor mode (Top view)”

• “Table 2.5.1 Relationship between processor modes and functions of P0 to P4”

_______

• “2.5.4 Relationship between access addresses and chip select signals (CS0–CS4) (This section is

added in part 2.)

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

• “2.5 Processor modes” (page 2–24 in part 1)
