Disable delay control. Connect to ground for normal operation.
In burst mode operation add a capacitor from this pin to ground to set the
maximum disable time. Disable times greater than this maximum will engage the
âslow-startâ circuitry.
Modulation Current Monitor. Connect to a resistor to GND.

The current through this pin is typically 1/50th of the MODULATION current to
the laser when CCSEL is low or 1/25th the MODULATION current when CCSEL is
high.
This pin may be left open if the feature is not needed and the M02094 current
consumption will be reduced by 0.5mA typically.
