8. Advanced Energy Monitor
When the CPT213B Capacitive Sense Evaluation Board is connected to a Silicon Labs STK, the STK's Advanced Energy Monitor
(AEM) hardware also measures the CPT213B power consumption using the VMCU connection on the EXP header. By using the [Ener-
gy Profiler] in Simplicity Studio, current consumption and voltage can be measured in real time.
More details about AEM and its operation can be found in the STK User Guide. Note that AEM will measure the current for all circuitry
connected to VMCU, including the STK MCU and the CPT device.
