3.1.1
The H8S/2655 Group has seven operating modes (modes 1 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 (MD
Table 3.1 lists the MCU operating modes.
Table 3.1
The CPU’s architecture allows for 4 Gbytes of address space, but the H8S/2655 Group 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.
