Configuration - Terasic DE0-Nano-SoC Edition Design Manual

SoC-FPGA Design Guide [DE0-Nano-SoC Edition]
examine the details of pin J18, to which
connected to 4 sources:

TRACE_D5

SPIS1_MOSI

CAN1_TX

HPS_GPIO54
This can be seen in Qsys, as shown in Figure 9-5.
Depending on how you configure the Peripheral Pins tab, you can configure pin J18 to use any of the sources
above. For example, if you want to use this pin as an SPI slave control signal, you would use the configuration
shown in Figure 9-6.
However, if you don't want to use any of the peripherals available at the top of the Peripheral Pins tab, then
you can always use one of the 2 buttons on the right side of Figure 9-5:

GPIOXY: Configures the pin to be connected to the HPS' GPIO peripheral.

LOANIOXY: Configures the pin to be connected to the FPGA fabric. This pin can be exported from
Qsys to be used by the FPGA.
