Bit 7: Phase Offset Recalibration (RECAL). When set to 1, this configuration bit causes a recalibration of the
phase offset between the output clocks and the selected reference. This process puts the DPLL into mini holdover,
internally ramps the phase offset to zero, resets all clock dividers, ramps the phase offset to the value stored in the
OFFSET registers, and then switches the DPLL out of mini-holdover. Unlike simply writing the OFFSET registers,
the RECAL process causes no change in the phase offset of the output clocks. RECAL is automatically reset to 0
when recalibration is complete. See Section 7.7.8.
0 = Normal operation
1 = Phase offset recalibration
Bits 6 to 4: External Frame-Sync Monitor Limit (MONLIM[2:0]). When the external frame-sync signal is
misaligned with respect to the MFSYNC output by the specified number of resampling clock cycles, a frame-sync
monitor alarm is declared in the FSMON bit of the OPSTATE register. See Section 7.9.6.

Bits 3 to 0: External Frame-Sync Reference Source (SOURCE[3:0]). When external frame sync is configured
for SYNC1 automatic mode, this field specifies the input clock to associate with the SYNC1 pin. See Section 7.9.1.
