Bits 7 to 4: Third Highest Priority Valid Reference (REF3[3:0]). This real-time status field indicates the third
highest priority validated input reference. When T4T0 = 0 in the
highest priority reference for the T0 DPLL. When T4T0 = 1, it indicates the third highest reference for the T4 DPLL.
Note that an input reference cannot be indicated in this field if it has been marked invalid in the
VALCR2
Bits 3 to 0: Second Highest Priority Valid Reference (REF2[3:0]). This real-time status field indicates the
second highest priority validated input reference. When T4T0=0 in the
second highest priority reference for the T0 DPLL. When T4T0=1, it indicates the second highest reference for the
T4 DPLL. Note that an input reference cannot be indicated in this field if it has been marked invalid in the
