DESCRIPTION
GPIO1
GPIO2 / IRQ
enabled only when pin not used as IRQ
GPIO3 / PENDOWN
enabled only when pin not used as PENDOWN
GPIO4 / ADA / MASK
enabled only when pin not used as ADA
GPIO5 / SPDIF_OUT
enabled only when pin not used as
SPDIF_OUT
GPIO Logic not implemented for these bits
Internal thermal cutout signal, indicates when
internal temperature reaches approximately
150C (see “Thermal Sensor”)
Internal ADA (ADC Data Available) Signal
enabled only when auxiliary 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
