API Call Reference List of APIs
OUTPUT The appropriate bit in the appropriate mask register is reset.
RETURN
OK If the bit was masked
ERROR if the bit was invalid
void frcDmaCompIntHandler (void)
This routine handles the DMA 0-3 completion interrupts. As soon
as the interrupt signal is active the CPU analyzes the MV DMA 0-3
Interrupt Cause register in order to locate the originating interrupt
event. Then the routine calls the user specified service routine for
that interrupt cause. The function scans the dma0_3Array[]
(dma0_3Count valid entries) trying to find a hit in the
dma0_3Array cause table.When found, the ISR in the same entry
is executed.
INPUT None.
OUTPUT If a cause bit is active and it's connected to an ISR function, the
function will be called.
RETURN None.
void frcDmaErrorIntHandler(void)
This routine handles the DMA 0-3 Error interrupts. As soon as the
interrupt signal is active the CPU analyzes the MV DMA 0-3 Interrupt
Cause register in order to locate the originating interrupt
event. Then the routine calls the user specified service routine for
that interrupt cause. The function scans the
dmaError0_3Array[] (dmaError0_3count valid entries) trying
to find a hit. When found, the ISR in the same entry is executed.
INPUT None.
OUTPUT If a cause bit is active and it's connected to an ISR function, the
function will be called.
RETURN None.
