Programmable Output Driver
The programmable output driver can be set to drive out differentially
200 to 1,400 mV. The differential output voltage (V
dynamically, or statically set by using the ALT2GXB megafunction or
through I/O pins.
The output driver may be programmed with four different differential
termination values:
