Power management

The MCA plays a key role in the power management activities of the ConnectCore 8X module. In
cooperation with the i.MX 8X processor, the MCA controls the power states of the PMIC and provides
multiple wake up sources to transition between power modes. It also allocates dedicated signals to
capture power events and indicate the system power state, allowing you to control external power
sources and indicators.
Power modes
The module provides four different power operating modes: ON/RUN, OFF, SUSPEND, and COIN-CELL.
The following figure shows the state diagram and the events to switch between states.
