SPI Mode

Mode  CPOL  CPHA
0     0     0     Clock idle low, data is clocked in on rising edge, output data (change) on falling edge
1     0     1     Clock idle low, data is clocked in on falling edge, output data (change) on rising edge
2     1     0     Clock idle high, data is clocked in on falling edge, output data (change) on rising edge
3     1     1     Clock idle high, data is clocked in on rising edge, output data (change) on falling edge

Using SPI bus master

//IN YOUR INITIALSE CODE
	//----- SETUP SPI 1 -----
	//Used for: 
	//Setup SPI using MCC:
	//	Setup SPI:
	//		(The following configures port for SPI Master Mode 3)
	//		Master Mode
	//		Clock Polarity Select Bit: Idle state is high, active state is low
	//		SPI Clock Edge Select Bit: Serial output data changesa on transition from Idle clock state to active clock state
	//		SPI Data Input Sample Phase Bit: Input data sampled at middle of data output time
	//		Master Mode Slave Select Enable Bit: Slave select SPI support is disabled
	//		Data Width: 8-bit
	//		Master Clock Enalbe Bit: PBCLK2 is used by the Baud Rate Generator
	//		Baud Rate in Hz: 1,000,000
	//		Dummy Data: 0xFF
	//	Setup interrupts:
	//		Enable SPI1 Fault Interrupt = Can be left set to Off
	//		Enable SPI1 Receive Done Interrupt = Will already be set to Enabled
	//		Enable SPI1 Transmit Done Interrupt: Will already be set to Enabled
	//		Priority (set for all): 1	//<<<Set as required for your application
	//		Subpriority (set for all): 0	//<<<Set as required for your application

	//SPI1_CallbackRegister(SPI1_MyEventHandler,(uintptr_t)NULL);		//Register my callback function to be called when the SPI operation completes (optional)


//HOW TO PERFORM A WRITE READ OPERATION
	uint8_t RxData[3];									//Can be uint8_t, uint16_t or uint32_t depending on your SPI port Data Width setting
	uint8_t TxData[3] = {0xff, 0xff, 0xff};				//Can be uint8_t, uint16_t or uint32_t depending on your SPI port Data Width setting
	if (SPI1_WriteRead(&TxData[0], 3, &RxData[0], 3))	//<<< RxData or TxData can be set as NULL and length to 0 if you don't care about the rx or tx side of the data transfer
	{
		//WRITE READ STARTED

		while (SPI1_IsBusy())
			;

		//WRITE READ COMPLETED


	}
