In both cases, depending on the value of the field Flash Low Power Mode (FLPM), the Flash enters three different
modes:
modes:
FLPM = 0 in Standby mode (Low consumption)
FLPM = 1 in Deep power-down mode (Extra low consumption)
FLPM = 2 in Idle mode. Memory ready for Read access
summarizes the power consumption, wake-up time and system state in wait mode.
5.5.3
Sleep Mode
The purpose of sleep mode is to optimize power consumption of the device versus response time. In this mode,
only the core clock is stopped. The peripheral clocks can be enabled. The current consumption in this mode is
application dependent.
only the core clock is stopped. The peripheral clocks can be enabled. The current consumption in this mode is
application dependent.
This mode is entered via Wait for Interrupt (WFI) or WFE instructions.
The processor can be awakened from an interrupt if the WFI instruction of the Cortex-M4 is used or from an event
if the WFE instruction is used.
if the WFE instruction is used.
