Setpoint 1
User 2,
trigger when Net >= Fixed43 (setpoint amount)
Configure the Setpoint 1 event with the Upper register = Fixed43 and the Lower register = Net
weight register. This will cause the setpoint to trigger when the Net weight >= (greater than or
equal to) the value in Fixed 43. Configure the Setpoint 1 function to execute = User 2.
Register Fixed43 is chosen because the fill amount is fixed. Data in the Fixed registers is written
to EA-ROM which remains unchanged by power loss.
