K10 FTM2 Set/GetOffsetTicks problems

the problem is that SetOffsetTicks doesn't work always. Function is called about once a second.

Quite often the new value doesn't go to HW, and readback by GetOffsetTicks returns the previous CnV value.

is there any knwon issue ni HW or PE-generated code?

Does FTM2 write erroneously the earlier value from cache register?


Checked the generated C code and disassemble-file, seems to be OK.

CPU revision is 0N96B, errata doesn't mention this kind of problem.


Added test counters:



They show that Set/Get functions are called correctly.
