1. The BusMatrix automatically is active when at least one master is ON (CPU or DMA1)

2. The APBx Bridge is automatically active when at least one peripheral is ON on the same 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.
