3.5 Pin Functions in Each Operating Mode
The pin functions of ports 1, 2, 3, 5, and 6 vary depending on the operating mode. Table 3-3
indicates their functions in each operating mode.

Notes: 1. Initial state. These pins function as an address bus by setting the corresponding DDR
bit to 1.
2. The functions of these pins vary depending on the settings in the wait state controller
enable register (WCER), wait control register (WCR), and port data direction register.
3.6 Memory Map in Each Operating Mode
Figure 3-1 shows a memory map of the H8/3032. Figure 3-2 shows a memory map of the
H8/3031. Figure 3-3 shows a memory map of the H8/3030. The address space is divided into
eight areas.
