TRMD = 0 (Receive mode)
If DMRQ = 1, the SSIRDR has unread data.
If SSIRDR is read, DMRQ = 0 until there is new
unread data.
TRMD = 1 (Transmit mode)
If DMRQ = 1, SSITDR requires data to be written to
continue the transmission to the audio serial bus.
Once data is written to SSITDR, DMRQ = 0 until it
requires further transmit data.
