resistors. The MCU-Link firmware triggers the switch back to low current measurements. The measurement circuit self-calibrates
each time the LPC55S36-EVK board is powered on. No user intervention is required to set up the calibration or adjust the
measurement ranges.
The measurement data can be displayed along with energy and power consumption data on the Energy Measurement view in the
MCUXpresso IDE. For more details on the MCUXpresso IDE, see

.

The power measurement feature is intended for low-power measurements, with a target MCU running at up to 3.6 V. The design
uses the LPC55S69 16-bit ADC, with power data sampled at up to 100 kS/s. The table below shows power/current measurement
range configuration settings. Maximum measurable current is 50 mA. Accuracy may vary with temperature and is provided for
reference purposes only.

3.9 MCU-Link status LEDs

The LPC55S36-EVK board has seven status indicator LEDs for MCU-Link. The table below lists these LEDs and describes how
each LED behaves in different MCU-Link modes.
