Does anyone know how long in clock cycles it takes for an interrupt to
be serviced form the time that the interrupt occurs?

Example code is provided for 56F801-7, 56F826-7 EVMs in support of
Low Voltage interrupts.

Here goes for CodeWarrior. I'm not using SDK. Disregard if you strictly want to use SDK.

What version of CodeWarrior are you using? I think it was version 5.0.2 or
5.0.3 that had problems with pragma interrupt, at least if you checked
