1. “Flash is in standby mode”, means the Flash is not accessed at all.
2. Low power consumption figures stated above cannot be guaranteed when accessing the Flash
in Ultra Low Power mode. In order to meet given low power consumption figures, it is recom-
mended to either stop the processor or jump to SRAM.
