Overview

Figure 6 shows an overview of the power management infrastructure. It consists of:

•

a power control unit (PCU) consists of:

–

the digital submodules PMC_dig

–

the analogue submodules PMC_ana

•

a clock generation module (MC_CGM)

•

a mode entry module (MC_ME)

Note:

For detailed information on these modules please refer to the respective chapters of the

reference manual.
