A protocol chain would then be defined as one or more layered protocols strung together and anchored by a base protocol. Our code only uses the GPIO, so it is not necessary to enable the SPI support in the raspi-config setup. It is an essential part of top-down digital design process. RTL on the other hand is a way of describing a circuit. if we do mirror the read data which is provied by rtl have put back to sequence by the driver then after it will compare with the ral model value i.
