A method includes receiving a chip select signal at an SPI client device. The method also includes, responsive to receiving the chip select signal, transmitting a first bit of an SPI transmission to an SPI host device, where the first bit of the SPI transmission is transmitted with a delay based at least in part on a loop propagation delay of an SPI channel. The method includes receiving a clock signal at the SPI client device. The method also includes, responsive to receiving the clock signal, transmitting a second bit of the SPI transmission to the SPI host device.

A Controller Area Network (CAN) transceiver determines a voltage differential signal from analog signaling and provides a digital output signal at a receiver output to a CAN controller based on the voltage differential signal. The analog signaling received from the CAN bus can operate with a first voltage level scheme of a first CAN protocol and a second voltage level scheme for a second CAN protocol. A first comparator compares the voltage differential signal to a first threshold which is set to a value which differentiates between a logic low bit and logic high bit in accordance with the second CAN protocol. Filtering circuitry selectively filters an output of the first comparator based on detection of noise on the CAN bus to provide a first digital signal indicative of activity on the CAN bus according to the second CAN protocol.
