1. A method, comprising:
receiving a chip select signal at a serial peripheral interface (SPI) client device;
responsive to receiving the chip select signal, transmitting a first bit of an SPI transmission to an SPI host device, wherein 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;
receiving a clock signal at the SPI client device; and
responsive to receiving the clock signal, transmitting a second bit of the SPI transmission to the SPI host device.
