Standard polarity / internally controlled integration time
When external polarity is set to standard and integration time is controlled by software, the falling
edge triggers the start of the integration time. The readout starts automatically once the configured
integration time has been elapsed. The rising edge of the signal is ignored.

Inverted polarity / externally controlled integration time
When external polarity is set to inverted and integration time is controlled by software, the rising edge
triggers the start of the integration time. The readout starts automatically once the configured
integration time has been elapsed. The falling edge of the signal is ignored.
