Urgent: Need help on Hard Fault

[0815]

I've read something about Hard Faults so far and I'm also using a Hard Fault Handler on my KEA128.

However I can't find the reason what is going wrong here.

This is the line of C code resulting in a Hard Fault:

FTM2_MODE = (FTM_MODE_FAULTM(0x00) | FTM_MODE_WPDIS_MASK);

I can debug this code in Disassembly View:

Actually I'm getting the Hard Fault directly on the first assembly instruction, but before it happend only on the 3rd instruction.

Any hints? Thanks in advance!

Is there a clock that needs turned on?

Some peripherals generate a hard fault if they are accessed without their clock running, some don't. 

I find that inconstancy annoying.  Just as annoying it is not documented in the Reference Manual which is which.

Yes, you are right!

SIM_SCGC |= SIM_SCGC_FTM2_MASK;

This does the magic.

Thank you, very much!
