1) This step of waiting is detailed in “1.5 Considerations in Reading and
Writing Time Data”.
*
1) This step is intended to select the level mode as a waveform mode for the
periodic interrupt function.
*
2) If this step is completed within 1 second, the step of waiting described in
“8.3-1 Ordinary Process of Reading Time and Calendar Data” above need
not be conducted. This step is detailed in “1.5 Considerations in Reading
and Writing Time Data”.
*
3) This step is intended to set the CTFG bit to 0 in the control register 2 to
cancel an interrupt to the CPU.
