However, if adding CGOUT and/or CDOUT, Time keeping Voltage and Current will be worse, and it will be hard
to oscillate. For reference, the data of Time keeping voltage and current when adding CGOUT=CDOUT=5pF
are shown in the table below.

Course (D)
It is necessary to select the crystal oscillator in the same manner as in Course (C) as well as correct errors in the
time count of each RTC in the same manner as in Course (B) by the method described in " P.32
Oscillation
Adjustment Circuit ".
*1) The CGOUT or/and CDOUT should have a
capacitance ranging from 0 to 6 pF.
