EXAMPLE 17-4: SPI1 ISR
/*
The following code example demonstrates a simple interrupt service routine for SPI1
interrupts. The user’s code at this vector should perform any application specific
operations and must clear the SPI1 interrupt flags before exiting.
*/
void __ISR(_SPI_1_VECTOR, ipl3) __SPI1Interrupt(void)
{
// ... perform application specific operations in response to the interrupt
IFS0CLR = 0x03800000;
}
// Be sure to clear the SPI1 interrupt flags
// before exiting the service routine.
Note:
The SPI1 ISR code example shows
MPLAB^® C32 C Compiler-specific syntax.
Refer to your compiler manual regarding
support for ISRs.
