Table 56 GPIO Bits and Pins
Note: GPIO7 (Pin 11) has an independent RESETB function. This must be disabled using RSTDIS (Register 5Ah, bit 8)
before using Pin 11 as a GPIO.

Internal microphone bias current detect, generates an interrupt above
a threshold (see MICBIAS Current Detect)
Internal shorted microphone detect, generates an interrupt above a
threshold (see MICBIAS Current Detect)
Internal thermal cutout signal, indicates when internal temperature
reaches approximately 150 C (see “Thermal Sensor”)
Internal ADA (ADC Data Available) Signal
enabled only when AUXADC is active
Internal COMP2 output (Low Battery Alarm)
enabled only when COMP2 is on
Internal COMP1 output (Dead Battery Alarm)
enabled only when COMP1 is on
