Current Measurement Option

The Current Measurement Option uses 0.025R ohm series resistors to measure the

current. The NS9210 Processor Module Development board allows to measure:

 the current used by the development board and module (through R80), and

 the current used by the internal NS9215 1.8V core generated from VLIO using a

high-efficiency synchronous step-down converter (through R81)
