Description
0:15 STARTUP RW R 0 Startup delay time -1 (in reference clock cycles), after
enable or DeepSleep wakeup, from reference clock
start to monitored clock start.
At a minimum (both clocks running): STARTUP >=
(PERIOD +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.
30 CSV_ACTION RW R 0 Specifies the action taken when an anomaly is
detected on the monitored clock. CSV in DeepSleep
domain always do a Fault report (which also wakes up
the system).
FAULT 0 Do a Fault report.
RESET 1 Cause a power reset. This should only be used for
clk_hf0.
31 CSV_EN RW R 0 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.
A CSV error detection is reported to the Fault
structure, or instead it can generate a power reset.
