Example for a single-cycle DMA transfer mode in receive direction (data is read from
DELIC and written to memory) in Intel/Infineon Mode.
1. The DMA mailbox contains data (the receive mailbox contains up to 16 bytes of data)
2. DELIC requests DMA service via DREQR
3. DMA controller issuses a DMA Acknowledge (DACK) signal for addressing the DMA
4. In parallel, when the read data are stable on the bus, the DMA controller writes the
Note: In Intel/Infineon Mode, WR is used as "read" signal for the receive mailbox.
