*/
The following code example will initialize the SPI1 in master mode.
It assumes that none of the SPI1 input pins are shared with an analog input.
If so, the AD1PCFG and corresponding TRIS registers have to be properly configured.
int rData;
IEC0CLR=0x03800000;
SPI1CON = 0;
rData=SPI1BUF;
IFS0CLR=0x03800000;
IPC5CLR=0x1f000000;
IPC5SET=0x0d000000;
IEC0SET=0x03800000;
SPI1BRG=0x1;
SPI1STATCLR=0x40;
SPI1CON=0x8220;
SPI1BUF=’A’;
INITIALIZATION FOR 16-BIT SPI MASTER MODE
// disable all interrupts
// Stops and resets the SPI1.
// clears the receive buffer
// clear any existing event
// clear the priority
// Set IPL=3, subpriority 1
// Enable Rx, Tx and Error interrupts
// use F
// clear the Overflow
// SPI ON, 8 bits transfer, SMP=1, Master Mode
// from now on, the device is ready to transmit and receive
// transmit an A character
