I am right now working with processors MCF 52235,52259 and 5329 and codewarrior as my IDE.I want to know what are the deafult or reset values for the real time clock registers. In the manual it has given as some arbitary value and with provided backup the RTC continues working even the power is off.                                 But when I tried resetting it all the values are turning to zero. By testing the power on rest with back up to the values are starting form the . Is there any idea.                                                               Can anyone help me with some info to help me test the power on reset for the RTC and verify that the RTC runs continously for the MCF 52235EVB which is not having any battery back up.                         Thanks for your time                                                                                                                                                                                                                                                                                                                                                                                                                                                                Latha
