32 bits transmit FIFO.
Table
Table
Selects the number of bytes in data as follows:
8 bit data
16 bit data
Reserved, do not use this setting
32 bit data
When one, data is of monaural format. When zero, the
data is in stereo format.
Disables accesses on FIFOs, places the transmit
channel in mute mode.
Asynchronously reset the transmit channel and FIFO.
When 0 master mode, when 1 slave mode.
Word select half period minus one, i.e. WS 64clk period
-> ws_halfperiod = 31.
Unused.
