This anomaly applies to Revision 2, build codes QFAA-C00, CAAA-C00, QDAA-C00, QGAA-C00.
It was inherited from the previous SoC revision Revision 1.
Symptoms
Current consumption increases when the device is in System ON all idle mode.
Conditions
- GPIO.PIN_CFN.SENSE is enabled, and GPIO.PIN_CFN.INPUT is connected.
- DETECT signal changes from low to high to low to high within 0.5 µs.
- SENSE condition remains active.
Consequences
Current consumption is approximately 300 µA higher than specified in System ON all idle mode.
Workaround
Apply one of the following workarounds:
- Avoid the DETECT signal changing from low to high to low to high within 0.5 µs.
- Enable latched mode by using GPIO:DETECTMODE = LDETECT.
