Description
Bypass and Power-Down Divider Logic; Route Clock Directly to Output (Default = 0b).
Not Used.
1 = Enable SYNC Detect (Default = 0b).
1 = Raise Flag if Slow Clocks Are Out-of-Sync by 0.5 to 1 High Speed Clock Cycles.
0 (Default) = Raise Flag if Slow Clocks Are Out-of-Sync by 1 to 1.5 High Speed Clock Cycles.
Soft SYNC bit works the same as the FUNCTION pin when in SYNCB mode, except that this bit’s
polarity is reversed. That is, a high level forces selected outputs into a known state, and a high >
low transition triggers a sync (Default = 0b).
1 = Power-Down the References for the Distribution Section (Default = 0b).
1 = Power-Down the SYNC (Default = 0b).

1 written to this bit updates all registers and transfers all serial control port register buffer
contents to the control registers on the next rising SCLK edge. This is a self-clearing bit. 0 does
not have to be written to clear it.
Not Used.
