H8S/2427, H8S/2427R, H8S/2425 Group
3.1
The H8S/2427 Group and H8S/2425 Group have six operating modes (modes 1 to 5, and 7). The
operating mode is selected by the setting of the mode pins (MD2 to MD0).
Modes 1, 2, and 4 are externally expanded modes in which the CPU can access an external
memory and peripheral devices. In an externally expanded mode, the external address space can
be designated as an 8-bit or 16-bit address space for each area by the bus controller at the
beginning of program execution. If a 16-bit address space is designated for any one area, the 16-
bit bus mode is selected. If an 8-bit address space is designated for all areas, the 8-bit bus mode is
selected.
Mode 7 is a single-chip activation expanded mode in which the CPU can switch to access an
external memory and peripheral devices at the beginning of program execution.
Mode 3 is a boot mode in which the flash memory can be programmed or erased. For details on
the boot mode, refer to section 23, Flash Memory.
Mode 5 is a user boot mode in which the flash memory can be programmed or erased. For details
on the user boot mode, refer to section 23, Flash Memory.
The settings for pins MD2 to MD0 should not be changed during LSI operation.
