mfrc630, clrc663 Change protocol problem -> my old question .


I have developed mfrc630 and clrc663 pre-product. all these board read and write mifare card well.

But, another protocol didn't. even to change iso14443a data rates speed. 

My procedure is 

load protocol cmd -> cmd load(read eeprom and write registers) cmd


I check my registers, these are same as manual.


what should I start first?
