MC9S12A64 + SPI interrupt + Processor Expert

I'm porting a codebase from an HC11 to a MC9S12A64 using Processor Expert to assist with getting the hardware layer completed quickly. Everything is working fine up to this point. I'm using Codewarrior 5.9.0 and Processor Expert 3.00 for HCS12


I want to utilize interrupt driven SPI but PE only seems to support polled. Everything else can utilize interrupts and I'm not understanding why it won't for this component. I CAN write the driver manually myself, however when I make changes to vector.c and events.c for example - the next time I compile, PE overwrites my changes. I don't want to turn off code generation yet as I still have more use of PE device drivers yet to be implemented but I would like this device to be up and working before proceeding.


Am I missing something or is there a way around this?
