How to configure SPE-APU feature into the MPC5644A microcontroller?

I need help for using hardware support for FINITE IMPULSE RESPONSE filters from the MPC5644A microcontroller.

At the moment,  FIR filter calculations are being done entirely on the software.

To optimize FIR filter, we want to integrate FIR hardware support (SPE-APU) into our project.


I would like to know:

How exactly do I integrate this FIR support from the SPE-APU into the SW project?

I tried to find the answer in the MPC5644A Microcontroller Reference Manual but I could not find how it should be done.


Thank you in advance for your assistance.
