TS-4100 FPGA DIO Table
From embeddedTS Manuals
The FPGA IO in Linux are GPIO 160-287. The crossbar mode indicates what this pin will output from the FPGA's perspective. For example, by default SPARE_4 outputs the value it samples from the WIFI_IRQ pin. WIFI_IRQ however is a GPIO so the FPGA can sample the input value.
