What is the ADKEY function?
Are there any reference materials available regarding the ADKEY function? [2009/08/05]
Similar to the key-on wakeup function, the ADKEY function is used to distinguish analog input voltage input from the ADKEY pin. When VIL (0.7 × VCC-0.5) or less is input, the A/D converter starts operating, and an A/D conversion interrupt can be used to distinguish analog voltage input.
For information on how to use the ADKEY function, please refer to the application notes below.
