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 access-
ing the Flash in Ultra Low Power Mode. In order to meet given low power consumption figures,
it is recommended to either stop the processor or jump to SRAM.
