Notes: 1. In modes 1 to 6, an 8-bit or 16-bit data bus can be selected on a per-area basis by
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 ABWCR settings. 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 and disable access to the on-chip ROM. Modes 1 and 2 support a maximum address space
of 1 Mbyte. Modes 3 and 4 support a maximum address space of 16 Mbytes.
