	== Toyota Protocol ==		== Background ==

			This interface was originally described as Toyota Sync Serial or "USART" by the first reverse engineering efforts. However once the datasheet for the onboard microcontroller was found, it was discovered that the datasheet refers to this interface as a Clocked Serial Interface (CSI). Each type of interface is referred to by letter, with "G" being assigned to the CSI, therefore it is referred to as the CSIG interface throughout the CPU datasheet.

			See the model-specific pages above for details on CPU part numbers and datasheets for more information.
