Normal operation
Cancel the remaining data transfer. Stop the executing channel and force the minor loop to finish. The
cancel takes effect after the last write of the current read/write sequence. The CX bit clears itself after
the cancel has been honored. This cancel retires the channel normally as if the minor loop was
completed.
Normal operation
Cancel the remaining data transfer in the same fashion as the CX bit. Stop the executing channel and
force the minor loop to finish. The cancel takes effect after the last write of the current read/write
sequence. The ECX bit clears itself after the cancel is honored. In addition to cancelling the transfer,
ECX treats the cancel as an error condition, thus updating the ES register and generating an optional
error interrupt.
Disabled. TCDn.word2 is defined as a 32-bit NBYTES field.
Enabled. TCDn.word2 is redefined to include individual enable fields, an offset field, and the NBYTES
field. The individual enable fields allow the minor loop offset to be applied to the source address, the
destination address, or both. The NBYTES field is reduced when either offset is enabled.
A minor loop channel link made to itself goes through channel arbitration before being activated
again.
A minor loop channel link made to itself does not go through channel arbitration before being
activated again. Upon minor loop completion, the channel activates again if that channel has a minor
loop channel link enabled and the link channel is itself. This effectively applies the minor loop offsets
and restarts the next minor loop.
Normal operation
Stall the start of any new channels. Executing channels are allowed to complete. Channel execution
resumes when this bit is cleared.
Normal operation
Any error causes the HALT bit to set. Subsequently, all service requests are ignored until the HALT
bit is cleared.
Fixed priority arbitration is used for channel selection.
Round robin arbitration is used for channel selection.
