2.3.2
Figure 2.4 indicates the data formats in memory. For access by the H8/300L CPU, word data
stored in memory must always begin at an even address. In word access the least significant bit of
the address is regarded as 0. If an odd address is specified, the access is performed at the preceding
even address. This rule affects the MOV.W instruction, and also applies to instruction fetching.
When the stack is accessed using R7 as an address register, word access should always be
performed. For the CCR, the same value is stored in the upper 8 bits and lower 8 bits as word data.
On return, the lower 8 bits are ignored.
