ABSTRACT:
Circuitry for monitoring operation of an optoelectronic device having a laser transmitter and a photodiode receiver includes analog to digital conversion circuitry for receiving a plurality of analog signals from the laser transmitter and photodiode receiver, converting the received analog signals into digital values, and storing the digital values in predefined memory-mapped locations within the optoelectronic device. Comparison logic compares one or more of these digital values with limit values, generates flag values based on the comparisons, and stores the flag values in predefined locations within the optoelectronic device. An interface enables a host device to read from and write to host-specified memory mapped locations within the optoelectronic device.
