Channel source frame index
-
Contains the channel source frame index, expressed as signed value in
bytes, which is used to compute addresses when double indexed ad-
dressing mode is used in DMA source port.
Function
Channel source element index
Channel source element index
-
Contains the channel source element index, expressed as signed value in
bytes, which is used to compute the addresses when single index ad-
dressing mode is used.
Function
Source element/frame address 16 LSB
This register can be used to monitor the progress of a DMA transfer on channel
source port:
It is a snapshot of the source address generated by the channel source
-
address counter, which is scheduled in the channel source port.
It is incremented on each access made on the channel source port (S8,
-
S16 or S32).
Note that in OMAP3.0/3.1 the address used by this register was dedicated to
DMA_CPC register, which does not exist anymore.
Function
Destination element/frame address 16 LSB
