NOTE
When an alternative function is first enabled, it is possible to get a spurious
edge to the module. User software must clear out any associated flags before
interrupts are enabled. Table 1 illustrates 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.
Disable all modules that share a pin before enabling another module.
