2.5.2
Figure 2.10 shows the data formats in memory. The H8S/2600 CPU can access word data and
longword data in memory, however 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, an address error does not
occur, however the least significant bit of the address is regarded as 0, so access begins 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 or
longword.
