5.10 GPIO
The SBC347A provides up to eight lines of GPIO, 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 Advanced Multiprocessor Integrated Software (AXIS) operation is
required, these signals cannot be used as GPIO. See
for more details.
NOTE
GPIOs are Only available when I/O product option = 1.
