I encounter a very strange issue about HDLC.

For the HDLC,  in my design, uses external clock, 

during debug,  find that, if feed the HDLC's rx/rx clock with different frequency clock, HDLC rx channel

will can not receive data any more.

Does it need to do some special setting for HDLC if RX/TX clock is different frequency?

Could you help to give some suggestions?
