Description
Monitor_DPLL_freq_soft_alarm
The Monitor DPLL has a programmable "soft" alarm
frequency limit. This is an alarm raised that does not
cause a disqualification of the input. This bit reports
the status of the "soft" alarm.
T4_DPLL_freq_soft_alarm
The T4 DPLL has a programmable "soft" alarm
frequency limit. This is an alarm raised that does not
cause a disqualification of the input. This bit reports
the status of the "soft" alarm.
sts_priority_table
Description
Highest priority validated source
Reports the input channel number of the highest
priority validated source.
Note that if an input is valid and it does not appear
in this field, then the input may have been
disallowed in register 30, 31h.
Register 4B, bit 4 must be set to ‘1’ for correct
setting and reporting of the T4 DPLL priorities.
Currently selected source
Reports the input channel number of the currently
selected source. When in Non-revertive mode, this is
not necessarily the same as the highest priority
validated source.
Note that if an input is valid and it does not appear
in this field, then the input may have been
disallowed in register 30, 31h.
This value will be the same as the highest priority
validated source.
Register 4B, bit 4 must be set to ‘1’ for correct
setting and reporting of the T4 DPLL priorities.
