29.1.2 Features
The MC_PCU includes the following features:
• Support for 3 power domains
• Support for device modes RESET, DRUN, SAFE, TEST, RUN0…3, HALT, STOP, and
STANDBY (for further mode details, please see the MC_ME chapter)
• Power states updating on each mode change and on system wakeup
• A handshake mechanism for power state changes thus guaranteeing operable voltage
• Maps the VREG registers to the MC_PCU address space
29.1.3 Modes of Operation
The MC_PCU is available in all device modes.
