METHOD FOR SERIAL PERIPHERAL INTERFACE (SPI) OPERATING-MODE SYNCHRONIZATION BETWEEN AN SPI HOST AND AN SPI DEVICE, AND SPI BUS SYNCHRONIZATION APPARATUS

摘要

The present invention provides a method for synchronizing a serial peripheral interface (SPI) operating mode between an SPI host and an SPI device, communicating over an SPI bus, for indicating, in the SPI device, a lack of synchronization of the SPI operating mode between the SPI host and the SPI device. It includes predefining one or more values of the SPI bus. Resynchronization of the SPI operating mode is initiated in response to receiving a predefined value from the SPI device.
