according to the pin state. Before changing the ICR setting, fix the pin state high or disable the
input function corresponding to the pin by the on-chip peripheral module settings.
pin state is reflected in all the inputs. Care must be taken for each module settings for unused
input functions.
if the input function corresponding to the pin is enabled. To use the pin as an output, disable
the input function for the pin by setting ICR.
Before enabling a port function, select the input/output destination.
To change input pins, the following procedure must be performed.
 Disable the input function by the corresponding on-chip peripheral module settings
 Select another input pin by PFCR
 Enable its input function by the corresponding on-chip peripheral module settings
bit that enables the pin function, first specify the input/output destination by the selection bit
and then enable the pin function by the enable bit.
