XVF 3800 SPI interface communication debugging problems

[huchangbai]

In the demo main program main. c（/modules/io/test/lib_spi/spi_slave_rx_tx/src） of the board，
The variables defined in the text include:
port_t setup_strobe_port = XS1_PORT_1E;
port_t setup_data_port = XS1_PORT_16B;
port_t setup_resp_port = XS1_PORT_1F;
What do they represent and what role do they play in communication（setup_strobe_port、setup_data_port、setup_resp_port）？

The file you reference is a test. These ports are just used for testing.
