Description
Power-down output (LVDS/CMOS).
<0> = 0; power on.
<0> = 1; power off.
In CMOS mode, <7:5> select the output polarity of each CMOS output.
In LVDS mode, only <5> determines LVDS polarity.

In CMOS mode, turn on/off the CMOS B output. There is no effect in LVDS mode.
<4> = 0; turn off the CMOS B output.
<4> = 1; turn on the CMOS B output.
Select LVDS or CMOS logic levels.
<3> = 0; LVDS.
<3> = 1; CMOS.
Set output current level in LVDS mode. This has no effect in CMOS mode.
