Backup mode overview
The V850ES/SA2 and V850ES/SA3 are put in backup mode by stopping supplying power other than the backup
power supply (V
DD
BU) in STOP mode.
The backup power supply supplies power only to the subclock oscillator, real-time counter, and internal RAM, as
shown in the figure below. Other on-chip functions including the CPU cannot operate since the power supply is
stopped.

In backup mode, subclock oscillator operation, real-time counter count operation, and internal RAM data
retention are enabled.
If the voltage is lower than the data retention voltage in backup mode, a backup power supply status flag (BPSF)
is set and that internal RAM retention data can be detected as invalid. When this flag is set, the real-time
counter and the RAM should be initialized at reset start.
