R/W
EN_SO
unused
DESCRIPTION
Enables the four frame strobe mode. The four frame strobe mode is used with
asynchronous serial or nibble data to identify words from each channel. TAG_22
in address 19 of the resampler control page must also be set. The two LSBs of
the tag words are used to generate the frame strobes. The output timing of the
frame strobes are the same as for SFS. If the Tag is 0, then a copy of SFS is
output as FSA, if the tag is 1, then a copy of SFS is output on FSB, if the tag is 2
then a copy of SFS is output on FSC, and if the tag is 3, then a copy of SFS is
output on FSD.
The output enable control for SO
