1. The power consumption of the analog part (IDDA) of peripherals such as ADC, DAC, Comparators, OpAmp etc. is not
included. Refer to the tables of characteristics in the subsequent sections.
2. BusMatrix is automatically active when at least one master is ON (CPU or DMA1).
3. The APBx bridge is automatically active when at least one peripheral is ON on the same bus.
