DS1807
Communication to activate or deactivate zero-crossing detection begins with a START condition which is
issued by the master device. The control byte from the master device will follow the START condition.
Once the control byte has been received by the DS1807, the part will respond with an
ACKNOWLEDGE. The read/write bit of the control byte, as stated, should be set equal to 0 for writing
the DS1807.
When the master has received the ACKNOWLEDGE from the DS1807, the master can then begin to
transmit the desired zero-crossing detection mode. Once the DS1807 has received the command byte, it
will respond with an ACKNOWLEDGE. At this point, the master device should respond with the STOP
condition.
