Disables or enables the switchover deglitch circuit.
0: enables switchover deglitch circuit (default).
1: disables switchover deglitch circuit.
If Register 0x01C, Bit 5 = 0, select reference for PLL.
0: selects REF1 (default).
1: selects REF2.
Sets method of PLL reference selection.
0: uses Register 0x01C, Bit 6 (default).
1: uses REF_SEL pin.
0: (default).
0: (default).
This bit turns the REF2 power on.
0: REF2 power off (default).
1: REF2 power on.
