Implementation

Interrupt Service Routines (ISR):

› The following ISRs are implemented to ensure a proper SPI communication in

DMA mode:

– SPI Master error interrupt ISR_qspi2_Er() ISR calls the function:

– IfxQspi_SpiMaster_isrError()

– SPI Slave error interrupt ISR_qspi3_Er() ISR calls the function:

– IfxQspi_SpiSlave_isrError()

– SPI Master transmit interrupt ISR_dma_ch1() ISR calls the function:

– IfxQspi_SpiMaster_isrDmaTransmit()

– SPI Master receive interrupt ISR_dma_ch2() ISR calls the function:

– IfxQspi_SpiMaster_isrDmaReceive()

– SPI Slave transmit interrupt ISR_dma_ch3() ISR calls the function:

– IfxQspi_SpiSlave_isrDmaTransmit()

– SPI Slave receive interrupt ISR_dma_ch4() ISR calls the function:

– IfxQspi_SpiSlave_isrDmaReceive()

› The functions listed above can be found in the iLLD headers IfxQspi_SpiMaster.h

and IfxQspi_SpiSlave.h
