The ‘ENABLE’ button controls the hardware enable if it is connected to LM10500.

The PWROK and Auth_OK are read-only bits, indicating the LM10500 has proper output voltage and

successful Authentication, respectively.

The PWI commands buttons send out commands to alter the operating state of the PWI slave: the

LM10500, authenticate and synchronize. Please refer to PowerWise Interface Specification for the details

of PWI standard at pwistandard.com.

A summary of the operation state is shown in Figure 7.
