NOTE: The recovery actions follow a many-to-one mapping. Each of the four columns in the table indicate error conditions and
each error condition has a unique metrics-mask to which multiple fault condition metrics can be mapped by 'OR'ing the metrics.
For example, in the matrix shown below, persistent error 0 looks for violation of lower thresholds from either indirect EVM,
mean TU power OR Peak Tx power, whereas persistent error1 looks for high threshold violations from indirect EVM only to
trigger a recovery action.
