Hi all, im working with the Kinetis Design Studio, Version: 3.2.0. Now im programming a routine that erases and writes Flash. I took some example Code and that works fine when i run it by singlestep "step into (F5)".

But when i let run it normally the MCU reboots suddenly as when he reaches the execute command:


FTFA_FSTAT = 0x80;      // write the CCIF Bit to clear it and start the command


All associated Interrupts are switched off. What is different in the singlestep mode ?
