5.2 On and Off Control OPERATION (01h) and ON_OFF_CONFIG (02h)
By default, ON_OFF_CONFIG (02h) is programmed to turn on and off by EN pin only as shown in Figure 5-3. To turn the device on and off using OPERATION (01h), change to either the second or fourth option to use I2C control. After selecting a new option in ON_OFF_CONFIG, click on Write to Hardware. Clicking on the OPERATION checkbox immediately writes 1 or 0 to OPERATION to turn on or turn off the device respectively.
