3.1
The H8S/2378 0.18μm F-ZTAT Group and H8S/2378R 0.18μm F-ZTAT Group have six
operating modes (modes 1 to 5 and 7). The H8S/2377 and H8S/2377R have five operating modes
(modes 1 to 4 and 7). The H8S/2375 and H8S/2375R has four operating modes (modes 1, 2, 4, and
7). The H8S/2373 and H8S/2373R has two operating modes (modes 1 and 2). The operating mode
is selected by the setting of 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 the externally expanded mode, each area can be switched to 8-
bit or 16-bit address space by the bus controller. If any one of the 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.
Mode 3 is a boot mode in which the flash memory can be programmed or erased. For details of the
boot mode, refer to section 21, Flash Memory (0.18-μm F-ZTAT Version), or section 20, Flash
Memory (0.35-μm F-ZTAT Version).
The settings for pins MD2 to MD0 should not be changed during operation.
