1) flash_program()

2) flash_Verfy

/******************************************************************************/
#pragma CODE_SEG RAM_CODE

unsigned char PFlash_Program(unsigned long address, unsigned short *ptr)
{
unsigned char i;
while((FSTAT & FSTAT_CCIF_MASK) == 0); //wait if command in progress
   FSTAT = 0x30;       //clear ACCERR and PVIOL
FCCOBIX = 0x00;
FCCOB = 0x0600 | ((address & 0x007F0000)>>16);
FCCOBIX = 0x01;
FCCOB = (address & 0x0000FFFF);
for(i=2; i<6; i++)
{
    FCCOBIX = i;
    FCCOB = 0xAA;
}

FSTAT = 0x80;       //launch command
while((FSTAT & FSTAT_CCIF_MASK) == 0); //wait for done

if((FSTAT & (FSTAT_ACCERR_MASK | FSTAT_FPVIOL_MASK)) != 0)
    return FlashProgramError;
else
    return noErr;
}
#pragma CODE_SEG DEFAULT

/******************************************************************************/

uint8_t FLASH_Read_Byte(uint8_t * Address)
{

return (*Address);
}

Hi tafeng,

when you launch debugger, click "Hotsync" button in P&E connection manager for each target connection.

The Hotsync button in the Connection Assistant allows the user to connect to an already running target. thus you can check the debugger memory window, if your flash is successful programmed.

Have a great day,
Jennie Zhang
