Section 2 CPU
In normal mode the memory operand is a word operand and the branch address is 16 bits long. In
advanced mode the memory operand is a longword operand, the first byte of which is assumed to
be all 0 (H'00). Note that the first part of the address range is also the exception vector area. For
further details, refer to section 5, 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.
