4.6SPIInterfaces
The SPI master provides a simple CPU interface which includes a TXD register for sending data and an RXD
register for receiving data. This section is added for legacy support for now.
The TXD and RXD registers are double-buffered to enable some degree of uninterrupted data flow in and out of the
SPI master.
The SPI master does not implement support for chip select directly. Therefore, the CPU must use available GPIOs
to select the correct slave and control this independently of the SPI master. The SPI master supports SPI modes 0
through 3.
