5.2.3 SPI Interface

The SPI plug-in demo is configured the SPI in target mode and other default settings as below:

  • Motorola 4 wire connection
  • Data captured on first clock edge
  • Clock polarity low
  • Bit order MSB

The demo’s operation details is similar with UART plug-in interface. For the step by step operation and how to debug the demo, see Section 5.2.1.1 and Section 5.2.1.2
