11.4.5 Changing INTRTC1 interrupt setting during clock 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 clock operation (PC1PWR = 1), in order to
mask the whiskers.
If the setting of the INTRTC1 interrupt (alarm interrupt) signal is changed while the real-time counter clock operates
Remark
See 21.3.4 Interrupt control register (xxICn) for details of the RTC1IF and RTC1MK bits.
