Input Sense Configuration
Figure 13-8. Synchronization when reading an externally applied pin value.
Input sensing is used to detect an edge or level on the I/O pin input. The different sense configu-
rations that are available for each pin are detection of rising edge, falling edge or both edges, or
detection of low level. High level can be detected by using inverted input. Input sensing can be
used to trigger interrupt requests (IREQ) or s when there is a change on the pin.
The I/O pins support synchronous and asynchronous input sensing. Synchronous sensing
requires presence of the peripheral clock, while asynchronous sensing does not require any
clock.
