(must be cleared in software)
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 should ensure
the appropriate interrupt flag bits are clear prior to enabling an interrupt. This feature
allows for software polling.
