1. A load control device, comprising:
a zero cross detection circuit operatively coupled to an alternating current (AC) supply voltage; and
a control circuit communicatively coupled to the zero cross detection circuit, the control circuit to:
receive, from the zero-cross detection circuit, an indication of a detected zero crossing of the alternating current (AC) supply voltage;
responsive to the detected zero crossing of the AC supply voltage, provide, for a charge time period (TCHRG) during one half of the AC cycle, a voltage to an operatively coupled remote dimmer circuit via an accessory dimmer (AD) conductor;
responsive to completion of the charge time period, provide a buffer time period (TBUFFER) during the one-half of the AC cycle;
responsive to completion of the buffer time period communicate a message using a defined communication format to the operatively coupled remote dimmer circuit via the AD conductor; and
responsive to completion of the communication of the message to the remote dimmer circuit, place the AD conductor in a high impedance state.
