1. alt_u32 slave is the number of slave connected to your master, with the first one starting from "0", as pointed out in the documentation.

So if I have 4 slaves connected to the SPI master, I should set slave =0x03? I think this argument is used to select which slave I want to write or read, e.g.: if I want to read or write slave 0, I should set slave = 0x00, correct?

Thanks.
