2.5.2
Figure 2.8 shows the data formats on memory. The H8/300H CPU can access word data and
longword data on memory, but word or longword data must begin at an even address. If an
attempt is made to access word or longword data at an odd address, no address error occurs but
the least significant bit of the address is regarded as 0, so the access starts at the preceding address.
This also applies to instruction fetches.
When ER7 (SP) is used as an address register to access the stack, the operand size should be word
size or longword size.
