WClkIO
These 3 bits select the format; see Table 65.
When WClkIO = 0, then WCLK is in Input mode. When WClkIO = 1, then WCLK is in
Output mode.
When BClkIO = 0, then BCLK is in Input mode. When BClkIO = 1, then BCLK is in
Output mode.
These 3 bits are reserved.

EBUValid
If EBUValid = 0, then EBU/IEC958 output data zero. If EBUValid = 1, then EBU/IEC958
output data valid.
If EBUOn = 0, then EBU/IEC958 output is switched off. If EBUOn = 1, then EBU/IEC958
output switched on.
These 2 bits are copied to bits 29 and 28 of the IEC958 control channel (crystal
accuracy); see Table 62.
