Section 2 CPU
Note that the first part of the address range is also the exception vector area. For further details,
refer to section 4, Exception Handling.
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 instruction code to be fetched
at the address preceding the specified address. (For further information, see section 2.5.2, Memory
Data Formats.)
Note: Normal mode is not available in this LSI.
2.7.9
Table 2.13 indicates how effective addresses are calculated in each addressing mode. In normal
mode the upper 8 bits of the effective address are ignored in order to generate a 16-bit address.
Note: Normal mode is not available in this LSI.
