2.7.5 Power Monitoring

The EVM includes integrated power monitoring/measurement capability for eleven (11) discrete power rails, giving user critical power usage details for optimizing the processor application. The on-board analog-to-digital converters (INA226) are accessed via I2C, and can be read both by the processor and externally via 3-pin header [J27]. Table 3-21 describes the I2C address and the power rail information of the ADC as is assigned. (Note, the Power Monitor I2C bus is a dedicated bus and can be access externally without impact to other I2C activity.)
