Bits 7 to 4: Highest Priority Valid Reference (REF1[3:0]). This real-time status field indicates the highest priority
valid input reference. When T4T0 = 0 in the MCR11 register, this field indicates the highest priority reference for
the T0 DPLL. When T4T0 = 1, it indicates the highest priority reference for the T4 DPLL. Note that an input
reference cannot be indicated in this field if it has been marked invalid in the VALCR1 or VALCR2 register. When
the T0 DPLL is in nonrevertive mode (REVERT = 0 in the MCR3 register) this field may not have the same value
as the SELREF[3:0] field. See Section 7.6.2.
0000 = No valid input reference available
0001–0010 = {unused values}
0011 = Input IC3
0100 = Input IC4
0101 = Input IC5
0110 = Input IC6
0111–1000 {unused values}
1001 = Input IC9
1010–1111 = {unused values}
Bits 3 to 0: Selected Reference (SELREF[3:0]). This real-time status field indicates the current selected
reference. When T4T0 = 0 in the MCR11 register, this field indicates the selected reference for the T0 DPLL. When
T4T0 = 1, it indicates the selected reference for the T4 DPLL. Note that an input clock cannot be indicated in this
field if it has been marked invalid in the VALCR1 or VALCR2 register. When the T0 DPLL is in nonrevertive mode
(REVERT = 0 in the MCR3 register) this field may not have the same value as the REF1[3:0] field. See Section
0000 = No source currently selected
0001–0010 = {unused values}
0011 = Input IC3
0100 = Input IC4
0101 = Input IC5
0110 = Input IC6
0111–1000 {unused values}
1001 = Input IC9
1010–1111 = {unused values}
