The Minimum Time Interval is the minimum amount of time that the Error Pin remains asserted (active low) when an enabled Error Event occurs. This value is system dependent, but time interval must be high enough so that the external monitoring agent can always detect the Error Pin asserted, but short enough so that if all of the Error Events are cleared, then the Error Pin can be de-asserted before the external agent decides to intervene. This is highly dependent on the application and the Fault Tolerant Time Interval.
The Minimum Time Interval counter is clock cycle based, therefore the time of the interval is a combination of the value in the Error Pin Counter Pre-Load Register and the clock frequency of the ESM. For Software configuration the value must be calculated accordingly. The Minimum Time Interval default value is set to 0xFF FFFF (for both modes: level and pwm (high and low minimum time interval values)), although this value can be changed according to the needs of the application after start-up.
