Figure 10. GPIO1 Tab

The GPIO1 tab (see Figure 10 ) selects options for the general-purpose inputs and outputs (GPIO) of theTLV320AIC3007.

The GPIO1 groupbox contains controls for setting options for the GPIO1 pin. The Function control selectsthe function of GPIO1 from the following:

•ADC Word Clock

•An output clock derived from the reference clock (see TLV320AIC3007 data sheet)

•Interrupt output pin to signal:

– Short Circuit– AGC Noise Threshold detection– Jack/Headset detection

•For use as an interrupt output, the behavior of the interrupt can be selected using the InterruptDuration control. A Single, 2ms pulse can be delivered when the selected interrupt occurs, orContinuous Pulses can be generated signaling the interrupt.

•Alternate I

2

S Word Clock

•A general-purpose I/O pin

– If selected as a General Purpose Input, the state of the GPIO1 pin is reflected by the Input Levelindicator. If selected as a General Purpose Output, the state of the GPIO1 pin can be set by usingthe Output Level button.
