3.5 Pin Functions in Each Operating Mode
The pin functions of ports 4 and 5 vary depending on the operating mode. Table 3-3 indicates their
functions in each operating mode.

Note: * Initial state. The bus mode can be switched by settings in ABWCR.
3.6 Memory Map in Each Operating Mode
Figure 3-1 shows a memory map for modes 1 to 4. The address space is divided into eight areas.
The initial bus mode differs between modes 1 and 2, and also between modes 3 and 4. The address
locations of the on-chip RAM and on-chip registers differ between the 1-Mbyte modes (modes 1
and 2) and 16-Mbyte modes (modes 3 and 4). The address range specifiable by the CPU in its 8-
and 16-bit absolute addressing modes (@aa:8 and @aa:16) also differs.
These pins function as P4
in 16-bit bus mode.
