I noticed a defect verified both in CCU4 and in CCU8, both on XMC1404 and on XMC4700.
The defect is as follows: I have to generate a pulse exactly 2 clock wide in both count directions, but when I count UP the pulse is right, but when I count DOWN the pulse becomes 3 clock wide.
When the count UP:
When the count DN:
I created a small project to prove the defect (see attached file): you can use the XMC1400 Boot Kit.
This is the configuration with DAVE:
Connect oscilloscope to outputs P1.0 (Clock output) and P1.1 (pulse output). Then use an electric wire connected to input P0.12 to reverse the counter direction (open: UP counter, connected to Vdd: DN counter).
Why does this happen? It's not normal. According to what is written in the reference manual of CCU4 (or CCU8) this anomaly should not occur.

Andrea

Why did no employee Infineon answer or verify this defect? Do not you think this is a bad problem?

Infineon lost interest in XMC?
Coming up on 3 years and no update.
