Applications differ in expected signal levels because of DC-coupled inputs, a broad selection of microphones to choose from, and flexibility in how those microphones are biased. Threshold programmability allows each fault to be set at a reasonable level and tailored to the application. The default values for these thresholds are set to be the most commonly used values. DIAG_CFG1 allows the user to configure the thresholds used for the INxP to INxM terminal short detection and the short to VBAT_IN detection.
