sts_interrupts
Description
Not used.
SEC2 valid change
Interrupt indicating that input SEC2 has become
valid (if it was invalid), or invalid (if it was valid).
Latched until reset by software writing a 1 to this bit.
SEC1 valid change
Interrupt indicating that input SEC1 has become
valid (if it was invalid), or invalid (if it was valid).
Latched until reset by software writing a 1 to this bit.
Not used.
sts_interrupts
Main_ref_failed
Description
operating_mode
Interrupt indicating that the operating mode has
changed. Latched until reset by software writing a 1
to this bit.
Main_ref_failed
Interrupt indicating that input to the T0 DPLL has
failed. This interrupt will be raised after 2 missing
input cycles. This is much quicker than waiting for
the input to become invalid. This input is not
generated in Free-run or Holdover modes. Latched
until reset by software writing a 1 to this bit.
Not used.
T4 ref valid change
Interrupt indicating that input T4 has become valid
(if it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
