Note 1: This bit can only be reset (=0), but cannot be set (=1).
Note 2: For SOFIC (address 0047

), a "0" should always be written.
Must always be set to "0"
When rewriting the interrupt control register, do so at a point that does not
generate an interrupt requst for that register. For details, see the interrupt
precaution section.
