I am using XMC4700 Relax Kit to evaluate the CCU8 concatenated Slice Timer counting. See attached DAVE code for the whole code.
1. I have 1 CCU8 Slice to generate a 12MHz clock, and then feed this clock into in0 of a 3 concatenated CCU8 Slices. The counting is trigged by event 0.
2. However, it turns out that this concatenated CCU8 timer counts 10 timer faster than expected.
3. When I switched to use concatenated 3 CCU4 slices to count the input in0 clock, it counts perfect.
Did I miss anything here?
Thank you so much!
