When I debug the program with step by step, the data can write P-Flash. But When I run the program in debug, it was paused in the FSTAT_CCIF = 1. When I check FSTAT register, I find it data was 00001000b.</P></BODY></HTML> Mon, 16 Apr 2018 07:10:26 GMT wangzhongyuan 2018-04-16T07:10:26Z Flash write https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Flash-write/m-p/734948#M14925 <HTML><HEAD></HEAD><BODY><P>I wanna write some data in P-Flash with MC9S12ZVCA192.
