1) Clock pulse of 32.768kHz or 32.000kHz is output from the
INTRB output pin on powering on (XSTP is set to 1).
*
2) Use a frequency counter having at least 6 digits (7digits or
more recommended).
*
3) Pull-up the INTRB output pin to V
DD
for the RS5C372A.
*
4) INTRB applies to the RS5C372A, and 32KOUT applies to the
RS5C372B. The RS5C372B does not need pull-up resistor.
2.3 Oscillation Frequency Adjustment
Adjustment amount of oscillation frequency may differ dependent on how the RS5C372A/B is used or how much
clock error is permissible in the system it is installed. Use the flow chart shown below find an optimal oscillation
frequency adjustment method.

1) In general crystal oscillators are classified by their central frequency of C
L
(load capacitance) and available further grouped in several ranks as ±10,
±20 and ±50ppm of fluctuations in precision.
*
2) Fluctuations in frequency due to the IC used is generally from ±5 to ±10ppm at a room temperature.
*
3) Clock precision here is at a room temperature and is subjected to change due to temperature characteristics of the crystal itself.
