12.4.5 Changing INTRTC1 interrupt setting during the real-time counter operation
(RC1PWR = 1), the INTRCT1 interrupt waveform may include whiskers and unintended signals may be output. Set as
follows when changing the setting of the INTRTC1 interrupt signal during the real-time counter operation (PC1PWR = 1,
RTCE = 1), in order to mask the whiskers.
