5.6.2 Notes on specifying the pin settings
For an output pin to which multiple functions are assigned, the output of the unused alternate functions must be
set to its initial state so as to prevent conflicting outputs. For details about the alternate function output, see 5.5
Register Settings When Using Alternate Function.
No specific setting is required for input pins because the output of their alternate functions is disabled (the buffer
output is Hi-Z).
Disabling the unused functions, including blocks that are only used for input or do not have I/O, is recommended
for lower power consumption.
