Figure 10. GPIO1 Tab
The GPIO1 tab (see
Figure 10
) selects options for the general-purpose inputs and outputs (GPIO) of the
TLV320AIC3107.
The
GPIO1
groupbox contains controls for setting options for the GPIO1 pin. The
Function
control selects
the function of GPIO1 from the following:
•
ADC Word Clock
•
An output clock derived from the reference clock (see
TLV320AIC3107
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
Interrupt
Duration
control. A
Single, 2ms
pulse can be delivered when the selected interrupt occurs, or
Continuous 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 Level
indicator. If selected as a
General Purpose Output
, the state of the GPIO1 pin can be set by using
the
Output Level
button.
