Description
Unused.
Description
Controls the output drive capability of the OUT1 driver.
0 = weak.
1 = strong (default).
Controls power-down functionality of the OUT1 driver.
0 = OUT1 active (default).
1 = OUT1 powered down.
OUT1 driver mode selection.
000 = CMOS, both pins active.
001 = CMOS, positive pin active, negative pin tristate.
010 = CMOS, positive pin tristate, negative pin active.
011 = CMOS, both pins tristate.
100 = LVDS.
101 = LVPECL (default).
110 = not used.
111 = not used.
Selects the polarity of the OUT1 pins in CMOS mode. This bit is ineffective unless Bits[5:3]
select CMOS mode. See the Output Driver Polarity (CMOS) section for the definition of
normal and inverted polarity.
0 = positive pin is normal polarity and negative pin is normal polarity (default).
1 = positive pin logic is inverted polarity and negative pin is normal polarity.
Unused.
Controls OUT1 driver functionality (see Figure 31).
0 = OUT1 mode determined by the OM2 to OM0 pins (default).
1 = OUT1 mode defined by Register 0x32[5:3].
