0x140
[7:5]
OUT4 output polarity
In CMOS mode, Bits[7:5] select the output polarity of each CMOS output.
In LVDS mode, only Bit 5 determines LVDS polarity.

4 OUT4 CMOS B In CMOS mode, turn on/off the CMOS B output. There is no effect in LVDS mode.
0: turns off the CMOS B output (default).
1: turns on the CMOS B output.
3 OUT4 select LVDS/CMOS Selects LVDS or CMOS logic levels.
0: LVDS (default).
1: CMOS.
[2:1] OUT4 LVDS output current Sets output current level in LVDS mode. This has no effect in CMOS mode.
