This section describes the procedure for transitioning the module state.
The following procedure is applicable for all LPSC-controlled modules. To transition the module state, one must be aware of several system considerations. Transitions between Enable and Disable states need to follow the procedure below. See the device-specific Datasheet and peripheral chapter for any other considerations especially while transitioning a module to Disable state. Also, before transitioning a module to Enable, if the logic/memories are not in the PD_WKUP and GP_CORE_CTL power domains, they must be turned on before or in parallel with the transition. See Section 5.2.2.3.1.5.1, Power Domain State Transitions.
The procedure for module state transitions is shown below (x denotes the power domain number, y denotes the module domain number):
