VDDA和VDDIO是否是同一个电源？
手册中Analog voltage range, VDDA
Supply voltage range, VDDIO (I/O and Flash)
ADC Connections if the ADC is Not Used
It is recommended that the connections for the analog power pins be kept, even if the ADC is not used.
Following is a summary of how the ADC pins should be connected, if the ADC is not used in an
application:
• VDDA – Connect to VDDIO
• VSSA – Connect to VSS
• VREFLO – Connect to VSS
• ADCINAn, ADCINBn, VREFHI – Connect to VSSA
VDDA – Connect to VDDIO 这点有点意外难道VDDA和VDDIO两个是连在一起的？
谢谢！
