MIC50395/50396/50397
If external capacitors on the BCD inputs are undesirable, it
will be necessary to synchronize the negative going edge of
the load register and/or load counter command to coincide
with the positive going edge of the scan input signal. Also
the V_SS range should be limited from 10.8 to 13.2 Volts.
Typically, the scan oscillator will oscillate at the following
frequencies with these nominal capacitor values from V_SS to
scan input.
