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 ?
