3.1
3.1.1
The H8S/2138 Group and H8S/2134 Group have three operating modes (modes 1 to 3). These
modes enable selection of the CPU operating mode and enabling/disabling of on-chip ROM, by
setting the mode pins (MD1 and MD0).
Table 3.1 lists the MCU operating modes.
Table 3.1
The CPU’s architecture allows for 4 Gbytes of address space, but the H8S/2138 Group and
H8S/2134 Group actually access a maximum of 16 Mbytes. However, as there are 16 external
address output pins, advanced mode is enabled only in single-chip mode or in expanded mode
with on-chip ROM enabled when a specific area in the external address space is accessed using
IOS. The external data bus width is 8 bits.
Mode 1 is an externally expanded mode that allows access to external memory and peripheral
devices. With modes 2 and 3, operation begins in single-chip mode after reset release, but a
transition can be made to external expansion mode by setting the EXPE bit in MDCR.
The H8S/2138 Group and H8S/2134 Group can only be used in modes 1 to 3. These means that
the mode pins must select one of these modes. Do not changes the inputs at the mode pins during
operation.
