Table A. GENERAL PURPOSE INPUT / OUTPUTs (GPIOs)
16 configurable logical Inputs and Outputs. All Inputs and Outputs are Active Low and are factory set to the following
signals. You can reassign any of these GPIOs to output or take as input a different signal. The GPIOs 15 and 16 are
logically mapped to the 1_GRT_CNL and 2_GRT_CNL of Lane1 and Lane2 connectors, respectively. You will have to
use the GND0 or GND1 from the GPIO terminal block.
