Section 1 CPU
1.5.2
Figure 1.11 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 is used as an address register to access the stack, the operand size should be word size
or longword size.
