space and the initial bus mode.
Table 3.1
Notes: 1. In modes 1 to 5, an 8-bit or 16-bit data bus can be selected on a per-area basis by
For the address space size there are three choices: 64 kbytes, 1 Mbyte, or 16 Mbyte. The external
data bus is either 8 or 16 bits wide depending on ABWCR settings. 8-bit bus mode is used only if
8-bit access is selected for all areas. 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.
