DMA Request Status Flag
This status flag allows the CPU to see the status
of the DMA request of SSI module.

If DMRQ = 1 then SSIRDR has unread data.
If SSIRDR is read then DMRQ = 0 until there
is new unread data.
If DMRQ = 1, SSITDR requests data to be
written to continue the transmission onto the
audio serial bus.
Once data is written to SSITDR then DMRQ =
0 until further transmit data is requested.
