Bits 3 and 2: Input Clock Valid Status (IC[3:2]). Each of these real-time status bits is set to 1 when the
corresponding input clock is valid. An input is valid if it has no active alarms (ACT = 0 in the ISR2 register). See
also the MSR1 register and Section 7.5.

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 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 6: Holdover Frequency Ready (HORDY). This latched status bit is set to 1 when the T0 DPLL has a holdover
value that has been averaged over the one-second holdover averaging period. HORDY is cleared when written
with a 1. When HORDY is set it can cause an interrupt request on the INTREQ pin if the HORDY interrupt enable
bit is set in the IER4 register. See Section 7.7.1.6.
Bit 5: Multiregister Access Aborted (MRAA). This latched status bit is set to 1 when a multibyte access (read or
write) is interrupted by another access to the device. MRAA is cleared when written with a 1. MRAA cannot cause
an interrupt to occur. See Section 8.3.
