Allows swapping of the transferred bytes, see
contains the bytes {a, b, c, d}. The following will be put into the FIFO for transmission:
0: {a, b, c, d}
1: {d, c, b, a}
2: {c, d, a, b}
3: {b, a, d, c}
Used only if the channel is in Descriptor Mode.
0: The descriptor read in is not the last descriptor in the chain. The next descriptor to be read is located at the address of the
previously read descriptor + 4 words.
1: The descriptor read in is the last descriptor in the chain. The next descriptor to be read is located at the address in the
Descriptor Start Address Register (DSARx) for the channel.
Used only if the channel is in Descriptor Mode.
0: The descriptor read in is not valid.
1: The descriptor read in is valid.
0: Transfer Complete does not set the ISR.CHxC bit.
1: Transfer Complete sets the ISR.CHxC bit.
Indicates the size of the burst used for data transfer. The MDMA will always try to use this burst size to perform transfers, but
may be forced to use smaller sizes since the transfer count may not be perfectly divisible by the transfer data size.
0: Single transfer
1: 4-beat burst
2: 8-beat burst
3: 16-beat burst
