0x01C 7
Disable
switchover
deglitch
Disables or enables the switchover deglitch circuit.
0: enables the switchover deglitch circuit (default).
1: disables the switchover deglitch circuit.
6
Select REF2
If Register 0x01C[5] = 0b, selects the reference for PLL when in manual; register selected reference control.
0: selects REF1 (default).
1: selects REF2.
5
Use REF_SEL pin If Register 0x01C[4] = 0b (manual), sets the method of PLL reference selection.
0: uses Register 0x01C[6] (default).
1: uses REF_SEL pin.
4
Enable automatic
reference
switchover
Automatic or manual reference switchover. Single-ended reference mode must be selected by Register 0x01C[0] = 0b.
0: manual reference switchover (default).
1: automatic reference switchover. Setting this bit also powers on REF1 and REF2 and overrides the settings in Register 0x01C[2:1].
3
Stay on REF2
Stays on REF2 after switchover.
0: returns to REF1 automatically when REF1 status is good again (default).
1: stays on REF2 after switchover. Does not automatically return to REF1.
2
Enable REF2
This bit turns the REF2 power on. This bit is overridden when automatic reference switchover is enabled.
0: REF2 power off (default).
1: REF2 power on.
1
Enable REF1
This bit turns the REF1 power on. This bit is overridden when automatic reference switchover is enabled.
0: REF1 power off (default).
1: REF1 power on.
0
Enable
differential ref
Selects the PLL reference mode, differential or single-ended. Register 0x01C[2:1] should be cleared when this bit is set.
0: single-ended reference mode (default); 1: differential reference mode.
