The H8S/2357 F-ZTAT can only be used in modes 4 to 7, 10, 11, 14, and 15. This means that the flash write enable pin
and mode pins must be set to select one of these modes.
Do not change the inputs at the mode pins during operation.
3.1.2
The H8S/2357 Group has 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 (MD
Table 3-2 lists the MCU operating modes.
Table 3-2
Notes: 1. In the H8S/2398 F-ZTAT, modes 2 and 3 indicate boot mode. For details on boot mode of the H8S/2398 F-
The CPU's architecture allows for 4 Gbytes of address space, but the H8S/2357 Group actually accesses 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 H8S/2357 Group cannot be used in modes 4 to 7. This means that the mode pins must be set to select 4 to 7 modes.
Do not change the inputs at the mode pins during operation.
