4.1.1

Supply Routing and Jumpers

The different MCU supply inputs are connected to the regulators on the motherboard through the
interface connector. Figure 13 shows how the MCU power domains are connected to the regulators.

Figure 13.

Daughter card power distribution

The connection of any power domain to a regulator has to be enabled by a dedicated jumper as described
in Table 8.
