ENTRY1_CHANNEL
R/W
This field indicates the channel number that is to be given an
opportunity to transfer data.
If this is a Tx entry, the DMA will be presented with a scheduling
credit for that exact Tx channel.
If this is an Rx entry, the DMA will be presented with a scheduling
credit for the Rx FIFO that is associated with this channel.
For Rx FIFOs which carry traffic for more than 1 Rx DMA channel,
the exact channel number that is given in the Rx credit will actually
be the channel number which is currently on the head element of
that Rx FIFO, which is not necessarily the channel number given in
the scheduler table entry.

encoded as follows:
