Data Sheet
Fast interrupt response
Independent interrupt systems for CPU and PCP
Each SRN can be mapped to the CPU or PCP interrupt system
Flexible interrupt-prioritizing scheme with 255 interrupt priority levels per interrupt
system
8 independent DMA channels
– 8 DMA channels in the DMA Sub-Block
– Up to 16 selectable request inputs per DMA channel
– 2-level programmable priority of DMA channels within the DMA Sub-Block
– Software and hardware DMA request
– Hardware requests by selected on-chip peripherals and external inputs
3-level programmable priority of the DMA Sub-Block at the on chip bus interfaces
Buffer capability for move actions on the buses (at least 1 move per bus is buffered)
Individually programmable operation modes for each DMA channel
– Single Mode: stops and disables DMA channel after a predefined number of DMA
– Continuous Mode: DMA channel remains enabled after a predefined number of
– Programmable address modification
– Two shadow register modes (with / w/o automatic re-set and direct write access).
Full 32-bit addressing capability of each DMA channel
– 4 Gbyte address range
– Data block move supports > 32 Kbyte moves per DMA transaction
– Circular buffer addressing mode with flexible circular buffer sizes
Programmable data width of DMA transfer/transaction: 8-bit, 16-bit, or 32-bit
Register set for each DMA channel
transfers
DMA transfers; DMA transaction can be repeated
