PCDATA
Note: when no use the low frequency oscillator, the PC2 can not use as a general port.
In PCM (Power Cut mode) mode, the general Port Function of PC2 can’t be used.
To use PC2 as a general port, please set GPIOCFR1<PC2F1>= 0y0, GPIOCFR2<PC2F2> =
0y0 and PMCCTL<PMCPWE> = 0y0, PMCWV1<PMCCTLV>=0y1 in the PMC function
and then the PMCCTL<PMCPWE> will be valid as “0” after to be read the bit of
PMCWV1<PMCCTLV> to “1”.
Note: about PC2 setting
This MCU implements power management circuit that can cut off power supply to circuit
blocks other than some special circuits and I/O pins. For details, please refer to PMC
