Change of interrupt factor
From among the ID numbers, ID Nos. 1 and 2 can be used to select, respectively, INTR2 pin / timer port and serial
interface / timer port / decreased voltage detection. These changes are made through the control port in each block.
Since selection is possible through the following settings, select according to the specification. These settings are also
made when routine initialization is being carried out. Do not perform the change while interrupt enable or interrupt
processing is in progress. Carry out any change in a state other than these states, and always reset the interrupt latch
after the change.
