1. A single-chip integrated circuit for controlling an optoelectronic transceiver having a laser transmitter and a photodiode receiver, comprising:

  • memory, including one or more memory arrays for storing information related to the transceiver;

    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 locations within the memory;

    control circuitry configured to generate control signals to control operation of the laser transmitter in accordance with one or more values stored in the memory;

    an interface for allowing a host to read directly from and write directly to locations within the memory; and

    comparison logic for comparing the digital values with limit values to generate flag values, wherein the flag values are stored in predefined locations within the memory during operation of the optoelectronic transceiver.
