Set the alternate functions in the following sequence.
<1> Set the PFCn and PFCEn registers.
<2> Set the PMCn register.
<3> Set the INTRn or INTFn register (to specify an external interrupt pin).
If the PMCn register is set first, an unintended function may be set while the PFCn and PFCEn
registers are being set.
