Thank you for help. I tried to say that hw configuration information from D0,D1 after reset is the same for 52234 and 52235. And the manual approves that. The CAU present bit is always zero.</DIV></BODY></HTML> Wed, 03 Sep 2008 15:22:10 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF52235-MCF52234-CAU/m-p/183430#M7580 BIS 2008-09-03T15:22:10Z
