Note: * Only modes 4 and 5 are provided in the ROMless version.
The CPU's architecture allows for 4 Gbytes of address space, but these versions actually access a
maximum of 16 Mbytes.
Modes 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 ROMless and Mask ROM versions can only be used in modes 4 to 7. This means that the
mode pins must be set to select one of these modes. However, note that only mode 4 or 5 can be
set for the ROMless version.
H8S/2339 F-ZTAT can only be used in modes 2 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.
