Switch S4 controls the data format options for both serial output ports, see Table 4 for switch configurations.
For SDOUT2, the output resolution will be equal to the resolution of the incoming receiver data. The excep-
tion is the case where right-justified mode is selected and the receiver input word-length is an odd number
of bits. In this case, the SDOUT2 word-length will be zero-stuffed to be 1 bit longer than the receiver input
word-length (example: a 19-bit receiver input word will result in an 20-bit right-justified serial format).
Note: The CS8406 does not support Right-Justified 20-bit resolution in hardware mode.
