5.6 GPIO Header
There is a 2x5 pin header(2.54mm) on the DE10-Advanced which connected to six FPGA HPS farbric GPIOs.These I/Os can be used as GPIO that are directly controlled by HPS. Or it can be used as SPI interface (HPS_DIO[11:8]), using the SPI master controller in HPS to communicate with other SPI devices.
