Digital Input Interrupt
All digital input channels can generate software interrupts (or events) to notice the
application about the state change of input signals. Interrupts can occur at rising
edge, falling edge, or both edges of the digital input signal as shown in Figure 3.3,
Figure 3.4, and Figure 3.5, respectively. The enable/disable interrupt function and the
selection of interrupt edges can be configured independently for each digital input
channel.
