8.3-3 Applied Process of Reading Time and Calendar Data Synchronized with Periodic Interrupt
Time data need not be read from all the time counters when used for such ordinary purposes as time count
indication. This applied process can be used to read time and calendar data with substantial reductions in the load
involved in such reading.
CTFG=1?

For Time Indication in “Day-of-month, Day-of-week, Hour,
Minute, and Second” Format:
*1) This step is intended to select the level mode as a waveform mode for the periodic interrupt function.
*2) This step must be completed within 0.5sec.
*3) This step is intended to read time data from all the time counters only in the first session of reading time data after writing time data.
*4) This step is intended to set the CTFG bit to 0 in the control register 2 to cancel an interrupt to the CPU.
