Function Documentation

void ConfigureSPIA	(	void(*)(void)	interruptRX,
		void(*)(void)	interruptTX,
		SPINMC	networkModeControl,
		SPILBK	spiLoopBack,
		Uint32	speed,
		Uint16	SPIcharLength,
		Uint16	txFIFO,
		Uint16	rxFIFO
	)

Intializes SPIA

Parameters:

	interruptRX,:	pointer to ISR executed when new data is received
	interruptTX,:	pointer to ISR executed when there is enough room in the txFIFO.
	networkModeControl,:	device as master or slave (SPIMASTER/SPISLAVE)
	spiLoopBack,:	enable/disable loopback mode (SPILBKENA/SPILBKDIS)
	speed,:	baud rate configuration in Mhz
	SPIcharLength,:	Character Length Control. Number of bits to be shifted in or out as a single character during one shift sequence.
	txFIFO,:	transmit FIFO interrupt level bits.
	rxFIFO,:	receive FIFO interrupt level bits.
