8. Typical Power Supply Circuit
1) Connect the capacitance of the oscillation circuit to the Vss pin.
2) Mount the high-and low-frequency by-pass capacitors in paral-
lel and very close to the RS5C316.
3) Connect the pull-up resistor of the INTR pin to two different
positions depending on whether the resistor is in use during
battery back-up.

...........Position B in the left figure
4) Timing of power-on, power-off and CE pin refer to following figure.
5) When a diode are in use in place of the components surround-
ed by dotted lines, note that applying voltage to any input pins
should be less than the rating of V

tky diode.

9. Oscillation Frequency Adjustment
9.1 Oscillation Frequency Measurement
1) Switch the CE pin to the high level and use a frequen-
cy counter to measure a 1Hz interrupt pulse output
from the INTR pin about 2.5 seconds later.
2) Ensure that the frequency counter has more than six
digits (on the order of 1 ppm).
3) Place the C

between the OSCIN pin and the VSS lev-
el and pull up the INTR pin output to the VDD.
