Modulation current control. Connect a resistor to ground to set the
modulation current.
Modulation current temperature compensation coefficient adjustment.
Connect a resistor to ground to set the temperature compensation
coefficient. Leave open to disable the temperature compensation.
A 51 kΩ resistor will result in a temperature compensation slope of
approximately 0.5%/°C.
Connect to GND.
