M68HC12B32EVB Interrupt Vector Table

Hi!
 
I am trying to use the real-time interrupt on this board, but the interrupt vector table is in a read-only section of the board. The EVB manual tells me to place the origin of the interrupts code at $F7F0 to use real time interrupts, but I cannot do it simply with the command:
 
ORG $F7F0
DC.W NAME_OF_LABEL
 
This gives me a "cannot write to memory" error when uploading the code. How can I set interrupts on this evaluation board. Neither the MCU's manual or EVB manual help in this regard. The board is running D-BUG 12 V2.0.1
 
Thanks for all and any help.
 
Christian
