12.10.1 INTCON
Note: Interrupt flag
bits are set when an Interrupt condition occurs, regardless of the state of its
corresponding enable bit or the Global Enable bit. User software may ensure the
appropriate interrupt flag bits are clear prior to enabling an interrupt. This feature
allows for software polling.
