Hello,
I suppose You use Codewarrior

You can save the routine ERASE_COM,WR_DATA_COM (included in the zip file form motorola) in a file .asm, for example Flash_Utility.asm in your project.

In another file (Flash.c) you can write the function like this

Code:
void Flash_Byte_Write(byte Data,unsigned int Address){ 
  //write to flash 
  .
  .
  .
  asm{   
    ldhx Address
    lda Data
    jsr WR_DATA_COM
  }
  .
  .
  .
}
 
void Flash_Page_Erase(unsigned int Address){ 
  asm{   
    ldhx Address   
    jsr ERASE_COM
  }     
}


One function is for erase the flash page and another one in for write a byte. Remember that You can Always Erase the page and then write the correct byte in that page.

OK ?
