*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 0.5 second.
*3) This step is intended to set the CTFG bit to 0 in the
Control Register 2 to cancel an interrupt to the CPU.
*1) When reading to clock and calendar counters, do not insert CE=L until
all times from second to year have been read to prevent error in reading
time. (Detailed in "P.24
