(4) Port 5 function control register (PFC5)
Caution When the P5n pin is specified as an alternate function by the PMC5.PMC5n bit with the
PFC5n bit maintaining the initial value (0), output becomes undefined. Therefore, to specify
the P5n pin as alternate function 2, set the PFC5n bit to 1 first and then set the PMC5n bit to
1 (n = 3 to 5).
