1. The BusMatrix is automatically active when at least one master is ON (CPU, DMA).
2. The APB Bridge is automatically active when at least one peripheral is ON on the Bus.
3. The power consumption of the analog part (I
DDA
) of peripherals such as ADC is not included. Refer to the
tables of characteristics in the subsequent sections.
