Question

 

What is the maximum clock rate for the ECI EPCA/PCA input?




Answer

 

When the external clock input (ECI) is selected as the EPCA clock source, the clock divider decrements on falling edges or both rising and falling edges of the pin. The ECI pin is synchronized to the selected AHB clock in this mode. The maximum clock rate for the ECI external clock input is the APB divided by 4.
