Hi,
The abnormal waveform of the PCLK is outputted such as following.
Conditions are following;
- The strapping option settings are;
clock source = clock, input reference clock frequency = 40MHz
- External oscillator frequency is 40MHz
- The PCLK can change into normal by RESETN
What is the cause of this abnormally waveform and the countermeasure?
Best Regards,
Kuramochi
