In “QUICC Engine BlockReference Manual with Protocol Interworking ” I found
the ratio between the HDLC interface serial clock frequency and the QUICC Engine clock frequency should be at least 1:14. but in the “P1021 QorIQ Integrated Processor Reference Manual" I found the ratio between the HDLC interface serial clock frequency and the QUICC Engine clock frequency should be at least 1:3.
In our P1012 platform, the QE frequency is 400MHz,if I use the External Clock,How to set the frequency of external clock for HDLC?
thanks!!!
Factory engineer confirmed the number 1:3 is correct.
I will notify documentation team to make appropriate changes in QE Reference Manual, thank you for pointing!
Have a great day,
Alexander
