Master/Slave Mode
This SPI controller can be set as master or slave mode by setting the SLAVE bit
(SPI_CNTRL[18]) to communicate with the off-chip SPI slave or master device. The application
block diagrams in master and slave mode are shown as below. This SPI controller does not
support multi-slave in SPI bus if the controller is set as slave mode.
