10.1.4 Monitoring Data
The DPMs can retrieve current, temperature, output voltage, and status information from each of the
POL converters and status information only from Auxiliary Devices. Monitoring data is stored in RAM
and can be accessed via the I2C bus. Monitoring registers are read only.
The monitoring data consists of 5 Bytes for each POL converter and Auxiliary Device as shown in Table
3. When the status monitoring is enabled, the ST registers get continuously updated. When the
parametric monitoring is enabled, the VOH, VOL, IO, and TMP registers get continuously updated.
