Bits 7 to 4: Priority for Input Clock 2 (PRI2[3:0]). Priority 0001 is highest; priority 1111 is lowest. When
MCR11:T4T0 = 0, PRI2 configures IC2’s priority for the T0 DPLL. When T4T0 = 1, PRI2 configures IC2’s priority for
the T4 path. See Section 7.6.1.
Bits 3 to 0: Priority for Input Clock 1 (PRI1[3:0]). Priority 0001 is highest; priority 1111 is lowest. When
MCR11:T4T0 = 0, PRI1 configures IC1’s priority for the T0 DPLL. When T4T0 = 1, PRI1 configures IC1’s priority for
the T4 path. See Section 7.6.1.

Bits 3 to 0: Priority for Input Clock 3 (PRI3[3:0]). Priority 0001 is highest; priority 1111 is lowest. When
MCR11:T4T0 = 0, PRI3 configures IC3’s priority for the T0 DPLL. When T4T0 = 1, PRI3 configures IC3’s priority for
the T4 path. See Section 7.6.1.
