→Power tree and voltage domains
* PMIC_PWRON (input): A rising edge of this pin (automatically done at startup) the PMIC performs an OFF-to-ACTIVE state transition. On a falling edge of this pin, the PMIC performs an ACTIVE-to-OFF state transition. This signal is pulled-up to VIN through 10kOhm resistor.
===Power tree and voltage domains===
Even if Diva is powered by one supply rail, several voltage domains exist according to circuitry and components' specifications.
From the system integrator's perspective, it is crucial to know how interface signals are related to these domains in order to design the carrier board properly.
The following image depicts Diva's simplified power tree and voltage domains organization. It also shows how voltage domains relate to the functional interfaces. For instance, iMX6's I2C1 signals belong to the I2C_PM_1.8V voltage domain that is detailed in section 4.1.3.3 on page 29.
TBD
The following tables detail electrical characteristics of the domains, in terms of nominal voltage and, for digital signals, of logic level thresholds.
