Note: Data is valid only if the output is decoupled from the 1-Wire input.  
ALL LINES OFF [66h]  
This command is used to deactivate the currently active 1-Wire output and to clear both event flags or to  
end a discharge cycle initiated by the Discharge Lines command. Before issuing this command, one  
should read the status and check the event flags of both, the main and the auxiliary output. Otherwise one  
might inadvertently clear the event flag without having taken appropriate action. If the DS2409 is in auto-  
control mode, the transistor at the control output will be switched off (non-conducting). At power-on, the  
device will automatically perform the All Lines Off command. In contrast to a power-on cycle, the All  
Lines Off command does not clear the Mode and Control Select bits.
