p1012 HDLC

[guxg]

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
