The most important point to note is to make sure that the desired pin-shared function is properly
selected and also deselected. For most pin-shared functions, to select the desired pin-shared function,
the pin-shared function should first be correctly selected using the corresponding pin-shared control
register. After that the corresponding peripheral functional setting should be configured and then the
peripheral function can be enabled. However, a special point must be noted for digital input pins,
such as INTn, xTCKn, xTPnI, etc, which share the same pin-shared control configuration with their
corresponding general purpose I/O functions when setting the relevant pin-shared control bits. To
select these pin functions, in addition to the necessary pin-shared control and peripheral functional
setup aforementioned, they must also be set as an input by setting the corresponding bit in the I/O
port control register. To correctly deselect the pin-shared function, the peripheral function should
first be disabled and then the corresponding pin-shared function control register can be modified to
select other pin-shared functions.
