Hi All,


We would like to read the GPIO triggerred by interrupt. So, we want to confirm which is the maximum frequency to read the GPIO?


We also find two articles in the community, but the information is so different.

=> It mentions 300 ns = 3333kHz.

=> The picture shows it's around 4.6kHz


Best regards,
