PRINCIPLES OF OPERATION
overflow flag for PCM
The PCM1804 has two overflow flag pins, OVFR (pin 20) and OVFL (pin 21). The pins go to high as soon as
the analog input goes across the full-scale range. The high level is held for 1.016 s at maximum, and returns
to low if the analog input does not go across the full-scale range for the period.
