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 accesing the Flash
1. Note: V
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.
