3.1
3.1.1
The H8S/2626 Group and H8S/2623 Group have four operating modes (modes 4 to 7). These
modes enable selection of the CPU operating mode, enabling/disabling of on-chip ROM, and the
initial bus width setting, by setting the mode pins (MD2 to MD0).
Table 3.1 lists the MCU operating modes.
Table 3.1
Note:
The CPU’s architecture allows for 4 Gbytes of address space, but the H8S/2626 Group and
H8S/2623 Group 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.
