This register only accepts 16-bit writing to prevent incorrect writing. In this case, the
upper eight bits of the data must be H'5A, otherwise writing cannot be performed.
When reading, read from the same address in bytes.

3. This register only accepts 32-bit writing to prevent incorrect writing. In this case, the
upper 16 bits of the data must be H'A55A, otherwise writing cannot be performed.
When reading, read from the same address in unit of 32 bits. At this time, the upper 16
bits are read as 0s.
