3.1 Overview
3.1.1 Operating Mode Selection
The H8/3002 has four operating modes (modes 1 to 4) that are selected by the mode pins (MD

Notes: 1. In all modes, an 8-bit or 16-bit data bus can be selected on a per-area basis by settings
For the address space size there are two choices: 1 Mbyte or 16 Mbytes. The external data bus is
either 8 or 16 bits wide depending on the settings in the area bus width control register (ABWCR).
If 8-bit access is selected for all areas, the external data bus is 8 bits wide. For details see
section 6, Bus Controller.
Modes 1 to 4 are externally expanded modes that enable access to external memory and peripheral
devices. Modes 1 and 2 support a maximum address space of 1 Mbyte. Modes 3 and 4 support a
maximum address space of 16 Mbytes.
The H8/3002 can only be used in modes 1 to 4. The inputs at the mode pins must select one of
these four modes. The inputs at the mode pins must not be changed during operation.
