EZ- PD™ PMG1 prototyping kit system design
3.3 EZ-PD™ PMG1 MCU subsystem
3.3.1 EZ-PD™ PMG1 MCU device
Visit the webpage or look at the device datasheets [4] to understand and compare the various features
supported by the EZ- PD™ PMG1 MCU controllers.
3.3.2 User LED and button
The user LED (green) is an EZ- PD™ PMG1 MCU-driven LED (LED3); you can configure the function through
firmware.
Table 11 lists the GPIO assigned for LEDs in each kit. The GPIOs need to be driven LOW to turn ON the user LED.
