Software selects the manual transfer method by setting the spi.Config [Man_start_en] bit = 1. In this mode, software must explicitly start the data transfer using the manual start command mechanism. When the [Man_start_en] bit = 0, the controller hardware automatically starts the data transfer when there is data available in the TXFIFO.
