Bits 7 to 4: Priority for Input Clock 4 (PRI4[3:0]). Priority 0001 is highest; priority 1111 is lowest. When
MCR11:T4T0=0, PRI4 configures IC4’s priority for the T0 DPLL. See section 7.6.1. When PRI4 is written with a
value > 0, IPR3:PRI6 will be forced to 0 (disabled).
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. See section 7.6.1. When PRI3 is written with a
value > 0, IPR3:PRI5 will be forced to 0 (disabled).
