Notes: 1. Because power supplies (1.2 V and 3.3 V) other than the 2.5-V power supply are
stopped in DDR-SDRAM power supply backup mode, all modules, except for pads of
the DDRIF module, are halted and their register information is not retained.
2. Because power supplies (1.2 V, 2.5 V, and 3.3 V) other than the RTC power supply are
stopped in RTC power supply backup mode, all modules other than the RTC module
are halted and their register information is not retained.
3. To enter both RTC and DDR-SDRAM power supply backup modes, satisfy the
transition conditions for both of them.
