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 touchpanel ADC is active
Internal PENDOWN Signal
enabled only when pen-down detection 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
