3.1
Operating Mode Selection
The H8S/2678 Group has twelve operating modes (modes 1, 2, 4 to 7, and 10 to 15). All operating
modes are available for the flash memory version. Modes 1, 2, and 4 to 7 are available in the
masked ROM version. Modes 1 and 2 are available in the ROMless version.
The H8S/2678R Group has seven operating modes (modes 1 to 7). All operating modes are
available for the flash memory version. Modes 1 and 2 are available in the ROMless version.
These modes are determined by the mode pin (MD2 to MD0) setting.
Modes 1, 2, and 4 to 6 are externally expanded modes in which the CPU can access an external
memory and peripheral devices. In the externally expanded mode, each area can be switched to 8-
bit or 16-bit address space by the bus controller. If one of areas is set to 16-bit address space, the
bus mode is 16 bits. If all areas are set to 8-bit address space, the bus mode is 8 bits.
Mode 7 is a single-chip activation externally expanded mode in which the CPU can switch to
access an external memory and peripheral devices at the beginning of a program execution.
Modes 3, 10, and 11 are boot modes in which the flash memory can be accessed.
Modes 12 to 15 are user program modes in which the flash memory can be accessed.
For details, refer to section 19, Flash Memory (F-ZTAT Version).
Do not change the FWE and MD2 to MD0 pin settings during operation.
