Abstract
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.
