Description
I3
Interrupt indicating that input I3 has become valid (if
it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
I2
Interrupt indicating that input I2 has become valid (if
it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
I1
Interrupt indicating that input I1 has become valid (if
it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
sts_interrupts
Description
MonDPLL_state
Interrupt indicating that the lock state of the Monitor
DPLL has changed. Latched until reset by software
writing a 1 to this bit.
Mon_ref_failed
Interrupt indicating that input to the Monitor 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.
I14
Interrupt indicating that input I14 has become valid
(if it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
I13
Interrupt indicating that input I13 has become valid
(if it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
I12
Interrupt indicating that input I12 has become valid
(if it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
I11
Interrupt indicating that input I11 has become valid
(if it was invalid), or invalid (if it was valid). Latched
until reset by software writing a 1 to this bit.
