Typical Characteristics: Current Consumption (continued)
Unless otherwise specified: VDD = 3.6 V, VEN = 3.3 V. Here are presented input current consumption measurements. Current
consumption is measured during a LED blink program execution. Program code sets every LED output to full PWM value for
2 seconds and then PWM is set to 0 for 2 seconds. This is looped endlessly. 750 measurements are taken during one
measurement cycle.

are Enabled During Program Execution.
