5.7.2
Dual BASE-T Variant (SBC329-xxx2xxxxx)
In this configuration, ETH0 and ETH1 are configured as 10/100/1000BASE-T.
ETH2 is not available in this configuration. The channels are connected to the VPX
P1 connector as follows:

5.8 GPIO
The SBC329 provides up to four lines of General Purpose I/O, each with interrupt
generation capabilities. Availability of the GPIO signals depends on the build
variant. The table below summarizes the availability and signal routing:

These are 3.3 V single-ended signals with 5 V tolerance. These signals are controlled
by the FPGA and can be configured as inputs, with the ability to generate level- or
edge-triggered interrupts.
The GPIO signals are intended only to be used by Abaco software drivers. See the
relevant software manual for details.
GPIO(2) and GPIO(3) are shared with the AXIS_CLK and AXIS_RST signals
respectively. If AXIS operation is required, these signals cannot be used as GPIO.
