Reserved. The default value for this register is 0x00. It is recommended to write a value
of 0x20 to this register.

7
Invert divider output
Inverts the polarity of the divider’s output clock.
6
Ignore sync
0: obeys chip-level SYNC signal (default).
1: ignores chip-level SYNC signal.
5
Power-down channel
1: powers down the entire channel.
0: normal operation.
4
Lower power mode
(differential modes only)
Reduces power used in the differential output modes (LVDS/LVPECL/HSTL). This
reduction may result in power savings, but at the expense of performance. Note that
this bit does not affect output swing and current, just the internal driver power.
1: low strength/lower power.
0: normal operation.
