Digital Diagnostic Monitor TX_FAULT Alarm/Warning Interrupt on page 37 for additional information on transceiver Digital Diag-
nostic Monitoring status.
bit will be set low after each first successful sampling occurs and remain low until the transceiver looses power or a failure occurs.
The bit must be set low within 1 second of reaching a valid stable power supply level.
lyze the status of the transceiver as an alternative to decoding the real-time values in bytes 96-105. Alarm flags indicate levels that
are likely to be associated with link failures. Warning flags indicate levels that are outside of normal levels, but not necessarily
cause for immediate concern (could be used for end-of-life indicators).
