STARTUP

0
Startup delay time -1 (in reference clock cycles), after
enable, from reference clock start to monitored clock
start.
At a minimum (both clocks running): STARTUP >=
(3) * FREQ_RATIO - UPPER, with
FREQ_RATIO = (Reference frequency / Monitored
frequency)
On top of that the actual clock startup delay and the
margin for accuracy of both clocks must be added.

Enables clock supervision, both frequency and loss.
CSV in Active domain: Clock supervision is reset
during DeepSleep and Hibernate modes. When
enabled it begins operating automatically after a
DeepSleep wakeup, but it must be reconfigured after
Hibernate wakeup.
CSV in DeepSleep domain: Clock supervision is reset
during Hibernate mode. It must be reconfigured after
Hibernate wakeup.
CSV in Backup domain: Clock supervision operates
during Hibernate mode, can be configured to wake
from Hibernate, and continues operating during reboot.
A CSV error detection is reported to the Fault
structure.
