I'm making a CAN Bootloader for mcs08dz128.
I have few questions about write flash in address:0xFF80~0xFFFF.
1). About Vector redirection,the address:0xFFBF,it's NVOPT=0x02,I know it should be set the FNORED bit to 0,&0xFFBD,it's NVPROT = FD,I set 0xE000~0xFFFF is protected.
Question:Should I set that in bootload progrom or in app progrom?or both.
When i need write those address from read .s19,how should I do?
2).The 0xFFFE~0xFFFF,it's reset by system?.s19 file has message to rewrite this address, should I egnore this address opreation?
3).0xFF80~0xFFFF,It's interrupt vectors.is there anyone who know How to operate those address clearly?Give me favour,please!
