Ultra low power
1. “Flash is in standby mode” means the Flash is not accessed at all.
Low power consumption figures found in the above table cannot be guaranteed when accessing the Flash in Ultra
Low Power Mode. In order to meet given low power consumption figures, it is recommended to either stop the pro-
cessor or jump to SRAM.
