1. This is a high current drive pin when operated as output.
2. This is a true open-drain pin when operated as output.
Note
When an alternative function is first enabled, it is possible to
get a spurious edge to the module. User software must clear any
associated flags before interrupts are enabled. The table above
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.
