8.4-1 Periodic Interrupt
*
1) This step is intended to select the level mode as a waveform mode for the
periodic interrupt function.
*
2) This step is intended to set the CTFG bit to 0 in the control register 2 to
cancel an interrupt to the CPU.
*
1) This step is intended to once disable the alarm interrupt circuit by setting
the WALE and DALE bits to 0 in anticipation of the coincidental occurrence
of a match between current time and preset alarm time in the process of
setting the alarm interrupt function.
*
2) This step is intended to enable the alarm interrupt function after completion
of all alarm interrupt settings.
*
3) This step is intended to once cancel the alarm interrupt function by writing
the settings of “
