• DMA Controlled Data Transfer (GMODE.EDMA=’1’)
If DMA operation is enabled, the SEROCCO-H autonomously requests data transfer to
the XFIFO by asserting the DRT line to the external DMA controller. The DRT line
remains active until the beginning of the last transmit data byte/word transfer. For a
detailed description of the external DMA interface operation refer to
“External DMA
Controller Support” on Page
