DCC Module Frequency Comparison can Report Erroneous Results

Details:

The Dual-clock Comparator module, which is used to monitor a clock frequency while comparing with a known clock reference, could stop earlier than expected, and, thus, indicating the measured clock frequency to be lower. This is due to a clock domain crossing issue causing a preset to the error detection logic to get triggered.

Workaround(s):

Application code, where possible, could compare the clocks using an alternate EDCC module (Present in MSS)

OR

Multiple measurements can be taken for the same clock pairs and abnormal frequencies reported can be ignored.

Work-around (1): Application code, where possible, could compare the clocks using an alternate EDCC module (Present in MSS)

Work-around (2): Multiple measurements can be taken for the same clock pairs and abnormal frequencies reported can be ignored.
