Yes, It is absolutly possible to erase and program flash in normal single
mode. But care should be taken to avoid accessing flash block which is being
erased or programmed (take care about interrupts for block 0 erase/program) lenux22 <> wrote: Hello, everybody!

Thank you for answer, but I still have a problem with flash program:
Here is the code: FCLKDIV = 0x5F; FCNFG = 0x0; FPROT = 0xFF; FSTAT = 0x30; FDATA = 0x0; FADDR = 0x0; FCMD = 0x41; //Mass erase FSTAT = 0x80; c = FSTAT; This code placed in RAM, and then I perform reset in Normal Single Chip mode with code dont work. But then I perform reset in Special Single Chip - all work fine, the mass-erase execute ok!
