Value Description
−32768 When DINDXMD = 0, DMACSEI is used as DMACEI; it contains the
to 32767 element index (in bytes) for both the source and the destination.
When DINDXMD = 1, DMACSEI contains the source element index
(in bytes).
Value Description
−32768 When DINDXMD = 0, DMACSFI is used as DMACFI; it contains the
to 32767 frame index (in bytes) for both the source and the destination.
When DINDXMD = 1, DMACSFI contains the source frame index (in
bytes).
