Chapter 2 External Signal Description

NOTE

When an alternative function is first enabled, it is possible to get a spurious

edge to the module. User software should clear out any associated flags

before interrupts are enabled. Table 2-1 shows the priority if multiple

modules are enabled. The highest priority module will have control over the

pin. Selecting a higher priority pin function with a lower priority function

already enabled can cause spurious edges to the lower priority module. It is

recommended that all modules that share a pin be disabled before enabling

anther module.
