Initialization/application information
21.5.2 Programming errors
The eDMA performs various tests on the transfer control descriptor to verify consistency
in the descriptor data. Most programming errors are reported on a per channel basis with
the exception of channel priority error (ES[CPE]).
For all error types other than channel priority error, the channel number causing the error
is recorded in the ES register. If the error source is not removed before the next activation
of the problem channel, the error is detected and recorded again.
If priority levels are not unique, when any channel requests service, a channel priority
error is reported. The highest channel priority with an active request is selected, but the
lowest numbered channel with that priority is selected by arbitration and executed by the
eDMA engine. The hardware service request handshake signals, error interrupts, and
error reporting is associated with the selected channel.
21.5.3 Arbitration mode considerations
21.5.3.1 Fixed channel arbitration
In this mode, the channel service request from the highest priority channel is selected to
execute.
