1.3
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. For details, see the hardware manual for the corresponding product.
