2.3
The H8SX CPU has two modes for instruction fetch: 16-bit and 32-bit modes. It is recommended
that the mode be set according to the bus width of the memory in which a program is stored. The
instruction-fetch mode setting does not affect operation other than instruction fetch such as data
accesses. Whether an instruction is fetched in 16- or 32-bit mode is selected by the FETCHMD bit
in SYSCR. For details, see section 3.2.2, System Control Register (SYSCR).
