Each digital channel includes a parametric measurement unit (PMU) which can be used to characterize and measure a digital pin’s DC characteristics. The PMU can be configured for force current, measure voltage, or force voltage, measure current. The PMU’s range of operation is listed below:
Force voltage range: -10 volts to +15 volts
Force current range: +/- 20 mA FS or +/- 200 mA FS
Measure voltage range: -10 volts to +15 volts
Measure current range: +/- 20 mA FS or +/- 200 mA FS
Measurement resolution is 16 bits for both voltage and current measurement functions. Note that while each channel has a dedicated PMU, the measurement resource is shared between all 32 channels, requiring sequential measurement of each channel.
