3.1
3.1.1
The H8S/2345 Group has eight operating modes (modes 4 to 7, 10, 11, 14 and 15). These modes
are determined by the mode pin (MD
CPU operating mode and initial bus width can be selected as shown in table 3.1.
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/2345 Group actually
accesses a maximum of 16 Mbytes.
