DMA Request Source
Encodes the source of DMA requests that trigger the DMA transfers. The DMA request
sources may be external devices requesting service through the IRQA, IRQB, IRQC and
IRQD pins, triggering by transfers done from a DMA channel, or transfers from the internal
peripherals. All the request sources behave as edge-triggered synchronous inputs.
Peripheral requests 18–21 (DRS[4–0] = 111xx) can serve as fast request sources. Unlike a
regular peripheral request in which the peripheral can not generate a second request until
the first one is served, a fast peripheral has a full duplex handshake to the DMA, enabling a
maximum throughput of a trigger every two clock cycles. This mode is functional only in the
Word Transfer mode (that is, DTM = 001 or 101). In the Fast Request mode, the DMA sets
an enable line to the peripheral. If required, the peripheral can send the DMA a one cycle
triggering pulse. This pulse resets the enable line. If the DMA decides by the priority
algorithm that this trigger will be served in the next cycle, the enable line is set again, even
before the corresponding register in the peripheral is accessed.
Three-Dimensional Mode
Indicates whether a DMA channel is currently using three-dimensional (D3D = 1) or
non-three-dimensional (D3D = 0) addressing modes. The addressing modes are specified
by the DAM bits.
