DSPI parameter configuration issue of SPC5

[Bwang.3]

Hello! I would like to ask what each of the three modes in the picture below represents?
Also, what does it mean if the GPIO parameter is set to PORT_1? I did not see that the GPIO bit 0 for this PORT_1 port is in use in the pin configuration editor! So I would like to ask if this parameter has been configured and used on this image?
Also, what does this PCS Line mean by choosing PCS1?
Is there a user manual for the parameter settings of DSPI for SPC582B! Because I want to know what the configuration parameters in the routine mean!
