13.2.2.4.1 Single Frame Transfer

In single frame transfer mode (shown in the following figure), the most significant byte of the FIFO transmit word is the control byte. The total data frame size supplied must be at least 12 bits long (8 bits for the control word and a minimum of 4 bits for data payload). Only the output data is sampled and inserted in the receive FIFO.
