To verify success, read the General Status Register at address 0215h. If MIP is 0, the command was executed
successfully.
MISSION EXAMPLE: PREPARE AND START A NEW MISSION
Assumption: The previous mission has been ended by using the Stop Mission command. Passwords are not
enabled.
Starting a mission with the DS2422 requires three steps:
Step 1: clear the data of the previous mission
Step 2: write the setup data to register page 1
Step 3: start the mission
STEP 1
Clear the previous mission.
With only a single DS2422 connected to the bus master, the communication of step 1 looks like this:
