Note: * Not used on ROMless version.
The CPU's architecture allows for 4 Gbytes of address space, but the H8S/2345 Series actually
accesses a maximum of 16 Mbytes.
Modes 1, 2, and 4 to 6 are externally expanded modes that allow access to external memory and
peripheral devices.
The external expansion modes allow switching between 8-bit and 16-bit bus modes. After program
execution starts, an 8-bit or 16-bit address space can be set for each area, depending on the bus
controller setting. If 16-bit access is selected for any one area, 16-bit bus mode is set; if 8-bit
access is selected for all areas, 8-bit bus mode is set.
Note that the functions of each pin depend on the operating mode.
The H8S/2345 Series can be used only in modes 1 to 7. This means that the mode pins must be
set to select one of these modes. Do not change the inputs at the mode pins during operation.
