3.1.1
The H8S/2357 F-ZTAT has eight operating modes (modes 4 to 7, 10, 11, 14 and 15). These modes are determined by the
mode pin (MD
selected as shown in table 3-1.
Table 3-1 lists the MCU operating modes.
Table 3-1
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.
Modes 10, 11, 14, and 15 are boot modes and user program modes in which the flash memory can be programmed and
erased. For details, see section 19, ROM.
The CPU's architecture allows for 4 Gbytes of address space, but the H8S/2357 Group actually accesses a maximum of 16
