I can read and write to all of the time and alarm registers and the contents are preserved by a lithium cell when power is removed. As I am not using the Timestamp facility I decided to use the Year-Timestamp register as "non-volatile memory", but when I write data to it , power off and read it at power up the data is not the same. Does anyone have any ideas?&nbsp;</P></BODY></HTML> Wed, 25 Oct 2017 11:36:26 GMT juliancox 2017-10-25T11:36:26Z PCA2129 https://community.nxp.com/t5/CodeWarrior-for-MCU/PCA2129/m-p/721564#M14248 <HTML><HEAD></HEAD><BODY><P>NOT SURE IF THIS IS THE CORRECT FORUM, BUT.....</P><P>I am using a PCF2129 real time clock with a S08QE and Processor Expert.
