2.5.2
Figure 2-8 shows the data formats in memory. The CPU can access word data and longword data in 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.
