The POL1 providing core voltage for MSC8156 has jumpers on 1.0 V power rail to isolate two cores
from six, for better power save. The Hall effect part in series with cores load is intend for current
measurement. The existing FPGA I
programming voltage. The DDR-2 port power supply is self-adjusted according to the type of DDR parts
inserted in the SODIMM. A DDR3 module requires a 1.5 V power supply, while the DDR2 module uses
a DDR3-DDR2 interposer card and the power supply applies 1.8 V. Vtt and Vref voltages are set
accordingly.
The U51 Hall current sensor device measures current consumption of the MSC8156 1.0V power supply.
