Power sequencing
Basically, VDD_IN is the first power domain to be turned on by the carrier circuit during power-up. Other circuit components on the carrier, which are galvanically
coupled to the module, shall not be supplied to avoid feedback. From the moment VDD_IN is stable - recognizable by VIN_PWR_BAD# deasserted - the module takes
over control of the power sequencing. As soon as the module reaches the next system state standby, CARRIER_PWR_ON signals the carrier to switch on all its standby
voltages. No feedback is provided to allow the carrier to signal Power OK to the modules power state machine. When the state Runtime is reached, the module de-
asserts CARRIER_STBY#. The carrier then switches on the remaining rails.
