Hi, Terry,

I think you can refer to the Flash example based on PE for MC56F8013, I attach the example here.

#pragma define_section RAW_PROG_FLASH_section ".RAW_PROG_FLASH" RX
#pragma section RAW_PROG_FLASH_section begin
static asm void Run_and_wait_in_prog_flash(IFsh1_TAddress address, word data, word command)
{
move.l A10,R2; /* Move given address to pointer register */
move.w Y0,p:(R2)+; /* Write data to the address in program memory */
move.w Y1,FMCMD_ASM;
move.w #$80,FMUSTAT_ASM;
wait:
moveu.w #$f020,R0;
adda #$3f3,R0,R0;
move.w X:(R0),A;
bftstl #$40,A1;
bcs wait;
rts;
}
#pragma section RAW_PROG_FLASH_section end
