Sir, I am learning SPI interfacing. I am using P89V51RD2FA microcontroller. And I have to interface it with a device using SPI interface but the problem is that I don't know what to do when I have to obtain data more than one byte.
Like in my case I need 3 bytes of data from the device. So after the usual write commands(giving command to read and the register to be read) and all, I am supposed to send some dummy byte which will be 0s. I wish to know that will the device return me three bytes just by one dummy byte or I need to send one dummy byte for each byte to be received.
