6 Blocks description

6.2.4.2 Ethernet DMA, Interrupt Sources Enable Register

Mnemonic

: DMA_INT_EN

Address

: 0x3000_3004

Default value

: 0x0000_0000

The DMA Interrupt enable register allows the various sources of interrupt to be individually

enabled.

All the enabled sources will then be OR-ed to generate the global DMA interrupt.

Setting a bit in DMA_INT_EN allows the corresponding interrupt described in DMA_INT_STAT

to influence the global DMA Interrupt.

If any bit position is set to '1' in BOTH DMA_INT_STAT and DMA_INT_EN, then the DMA

Interrupt will be asserted.

Refer to the DMA_INT_STAT for a description of interrupt sources.
