Supply Routing and Jumpers 

The  different  MCU  supplies  are  connected  to  the  regulators  on  the  Mother  Board  through  the 
interface connector. Also daughter card has option to connect MCU supplies to either Mother Board 
supplies or onboard regulators. 

Figure 11 

shows how the MCU power domains are connected to the 

regulators.
