Section 2 CPU
If an odd address is specified in word or longword memory access, or as a branch address, the
least significant bit is regarded as 0, causing data to be accessed or an instruction code to be
fetched at the address preceding the specified address. (For further information, see section 2.5.2,
Memory Data Formats.)
2.7.2

Table 2.6 indicates how effective addresses are calculated in each addressing mode. In normal
