Bit 5: Activity Alarm for Input Clock 4 (ACT4). This real-time status bit is set to 1 when the leaky bucket
accumulator for IC4 reaches the alarm threshold specified in the LBxU register (where x in LBxU is specified in the
BUCKET field of ICR4). An activity alarm clears the IC4 status bit in the VALSR1 register, invalidating the IC4
clock. See Section 7.5.2.
Bit 4: Phase-Lock Alarm for Input Clock 4 (LOCK4). This status bit is set to 1 if IC4 is the selected reference
and the T0 DPLL cannot phase lock to IC4 within the duration specified in the PHLKTO register (default = 100
seconds). A phase-lock alarm clears the IC4 status bit in VALSR1, invalidating the IC4 clock. If LKATO = 1 in
MCR3, LOCK4 is automatically cleared after a timeout period of 128 seconds. LOCK4 is a read/write bit. System
software can clear LOCK4 by writing 0 to it, but writing 1 is ignored. See Section 7.7.1.
Bit 1: Activity Alarm for Input Clock 3 (ACT3). This bit has the same behavior as the ACT4 bit but for the IC3
input clock.
Bit 0: Phase-Lock Alarm for Input Clock 3 (LOCK3). This bit has the same behavior as the LOCK4 bit but for the
IC3 input clock.
