1. The BusMatrix is automatically active when at least one master is ON (CPU, DMA).

2. The GPIOx (x= A…F) dynamic current consumption is approximately divided by a factor two versus this table values when

the GPIO port is locked thanks to LCKK and LCKy bits in the GPIOx_LCKR register. In order to save the full GPIOx current

consumption, the GPIOx clock should be disabled in the RCC when all port I/Os are used in alternate function or analog

mode (clock is only required to read or write into GPIO registers, and is not used in AF or analog modes).

3. The AHB to APB1 Bridge is automatically active when at least one peripheral is ON on the APB1.

4. Independent clock domain.

5. Clock domain.

Wake-up time from low-power modes and voltage scaling transition times

The wake-up times given in Table 45 are the latency between the event and the execution of the first user

instruction.

The device goes in low-power mode after the WFE (Wait for event) instruction.

Table 45. Low-power mode wake-up timings

Evaluated by characterization, not tested in production.
