3.2.4.4.4 Flow of Controlling Event Detection when used as Interrupt
When you use the results of event detection as interrupts (refer to 3.2.4.4.1), for setting Event Detection and
clearing the status register, follow the flow shown below. Figure General Purpose Input/Output (GPIO)-23 shows
a connection diagram of event detection function and SYSCPU or DSP.
