よくある質問
Why can’t the GPIO PA0 and PA1 pins in the NuMicro® NUC442/NUC472 series be normally output to the High voltage level? 日付:2016-08-18
Since the power source of GPIO PA.0 and PA.1 pins in the NUC442/NUC472 series is from the VBAT pin, different from the power supply of other GPIO pins from VDD. Thus, it is necessary to provide a constant power supply to the VBAT pin. The VBAT pin shall not be floating; otherwise, the PA.0 and PA.1 pins cannot be output to the High voltage level.
The following shows the NUC442/NUC472 series power distribution diagram.
