Method and apparatus for enhanced modes in SPI communication

摘要

A method for full duplex data transference between a master device and a slave device comprises the steps of the slave device providing (725) data stored in a location within the slave device to the master device and the master device providing (760) modified data to be stored in the location to the slave device. A further step includes the slave device, substantially coincident with the master device providing (760) the modified data to the slave device, providing (755) data stored in a subsequent location within the slave device to the master device.
