TCLEAR_FLAG
Time from sending the
CLEAR to deassertion on
FLAG
1. The timing does not impact the user design, but it is useful for security analysis.
2. System service requests from the fabric will interrupt the system controller delaying the generation of
the flag.
3. Timing of these depends highly on supply ramp rate.
