Section 1 CPU
1.5.2
Figure 1.11 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 the stack pointer (ER7) is used as an address register to access the stack, the operand size
should be word size or longword size.
