104 Direct Memory Access (DMA) Support
This register can be used to monitor the progress of a DMA transfer on channel
destination port:
It is a snapshot of the destination address generated by the channel
-
destination address counter, which is scheduled in the channel destination
port.
It is incremented on each access made on the channel destination port
-
(S8, S16 or S32).
Function
Channel destination element index
Channel destination element index
-
Contains the channel destination element index, expressed as a signed
value in bytes, which is used to compute the addresses, when single/
double indexed addressing mode is used.
Note:
When DMA_ CCR[10] = 1, then destination_element_index = DMA_CDEI.
When DMA_ CCR[10] = 0, then destination_element_index = DMA_CSEI.
Function
Channel destination frame index
Channel destination frame index
-
Contains the channel destination frame index, expressed as a signed val-
ue in bytes, which is used to compute the addresses when double indexed
addressing mode is used.
Note:
When DMA_CCR[10] = 1, then destination_frame_index = DMA_CDFI
When DMA_CCR[10] = 0, then destination_frame_index = DMA_CSFI
