void frcDmaIntCtrlInit(void)
INPUT None.
2. User ISR connecting. Here information about user ISR and
interrupt priority is gathered. Composed of vxDmaIntConnect()
routine.
3. Interrupt handler. Here an interrupt is being handle by the
Interrupt Handlers (driver's ISR). Composed of vxDmaInt()
This routines connects the drivers interrupt handlers, each to its
corresponding bit in the MV main Interrupt Controller using the
gtIntConnect() routine.
OUTPUT The DMA Engine cause & mask register are initiated (set to zero).
Driver's ISR are connected to the main cause register. Interrupts
are unmasked.
RETURN None.
STATUS frcDmaIntConnect(DMA_CAUSE cause, VOIDFUNCPTR routine, int parameter, int
prio)
This routine connects a specified user ISR to a specified MV DMA
interrupt cause (0x8c0 or 0x9c0).Each ISR handler has its own user
ISR array. The connection is done by setting the desired routine
and parameter in the corresponding cause array (i.e.
dma0_1Array[ ])
Locating the correct Array to make the connection. This is
made according to the cause. DMA channel completion events
has unique ISRs.
Check for existing connection for the cause bit in the table.
Connecting the user ISR by inserting the given parameters into
an entry according to the user ISR given priority.
INPUT
cause DMA interrupt cause. See DMA_INT_CAUSE.
routine User ISR.
parameter User ISR parameter.
