2.6.2
Figure 2.13 shows the data formats in memory.
The H8SX CPU can access word data and longword data which are stored at any addresses in
memory. When word data begins at an odd address or longword data begins at an address other
than a multiple of 4, a bus cycle is divided into two or more accesses. For example, when
longword data begins at an odd address, the bus cycle is divided into byte, word, and byte
accesses. In this case, these accesses are assumed to be individual bus cycles.
However, instructions to be fetched, word and longword data to be accessed during execution of
the stack manipulation, branch table manipulation, block transfer instructions, and MAC
instruction should be located to even addresses.
When SP (ER7) is used as an address register to access the stack, the operand size should be word
size or longword size.
