7.6 Carkit DP interrupt detector
The DP pull-down resistor (R
the Resistor Control register is set.
The DM pull-down resistor (R
in the Resistor Control register is set.
The built-in DC-DC regulator conditions the input power supply (V
the ISP1109.
When V
than 3.6 V, the regulator will be bypassed and pin REG3V3 will be shorted to pin V
The output of the regulator can be monitored on pin REG3V3. A capacitor (0.1 F) will be
connected to pin REG3V3.
The carkit DP interrupt detector is a comparator that detects the carkit interrupt signal on
the DP line in analog audio mode. Bit DP_INT will be cleared (set to logic 0), if the voltage
level on the DP line is below the carkit interrupt threshold V
The carkit interrupt detector is enabled in audio mode only (bit AUDIO_EN = 1).
