Section 3 MCU Operating Modes
3.5 Pin Functions in Each Operating Mode
The pin functions of ports 1 to 3, port 5 and port A vary depending on the operating mode. Table
3.3 indicates their functions in each operating mode.

2. Initial state. These pins become address output pins when the corresponding bits in the
data direction registers (P1DDR, P2DDR, P5DDR) are set to 1.
3. Initial state A₂₀ is always an address output pin. PA₆ to PA₄ are switched over to A₂₃ to
A₂₁ output by writing 0 in bits 7 to 5 of ADRCR.
3.6 Memory Map in Each Operating Mode
Figure 3.1 shows a memory map of the H8/3039. Figure 3.2 shows a memory map of the H8/3038.
Figure 3.3 shows a memory map of the H8/3037. Figure 3.4 shows a memory map of the H8/3036.
The address space is divided into eight areas.
Modes 1, 3 and 5 are the 8-bit bus mode.
The address locations of the on-chip RAM and on-chip registers differ between the 1-Mbyte
modes (modes 1, 5, and 7) and 16-Mbyte mode (mode 3), and 64-kbyte mode (mode 6). The
address range specifiable by the CPU in the 8- and 16-bit absolute addressing modes (@aa:8 and
@aa:16) also differs.
