In GPIO mode, this pin indicates whether the device is in the USB Suspend or
not. The polarity can be configured via the configuration PROM, and defaults
to active-low.
In modem control mode, this pin is the Ring Indicator control input (active low)
for the Standard Comm Interface.
In GPIO mode, this pin is a user-configurable input or output for the Standard
Comm Interface.
In modem control mode, this pin is the Data Carrier Detect control input
(active low) for the Standard Comm Interface.
In GPIO mode, this pin is a user-configurable input or output for the Standard
Comm Interface.
In modem control mode, this pin is the Data Terminal Ready control output
(active low) for the Standard Comm Interface.
In GPIO mode, this pin is a user-configurable input or output for the Standard
Comm Interface.
In modem control mode, this pin is the Data Set Ready control input (active
low) for the Standard Comm Interface.
Asynchronous data output (UART Transmit) for the Standard Comm Inter-
face.
Asynchronous data input (UART Receive) for the Standard Comm Interface.
Ready to Send control output (active low) for the Standard Comm Interface.
