Current Shunt Resistor

If current shunt resistor is connected between GND_X to GND or PVDD_X to PVDD, make sure there is only one
single path to connect each GND_X or PVDD_X pin to shunt resistor, and the path is short and symmetrical on
each sense path to minimize the measurement error due to additional resistance on the trace.
