External ADC clock

Hello,
I cannot get working an external Clock to the ADC component in an SLG46620 project.
I have selected "EXT.CLK2" in the ADC Properties and figured out that CLK2 is available in the Matrix2 OSC component, that I have routed to input Pin12 (see attached pictures).
During emulation, OSC debug output Pin15 correctly show the Pin12 input square wave, thus confirming that the external clock is functioning.
Unfortunately ADC debug output Pin4 routed to ADC's "INT.OUT" pin is stuck at low level, indicating that no ADC conversions are taking place.
What am I missing or what am I doing wrong ?

Many thanks in advance,
Marco

Hi Ibelvo,

Hi Ibelvo,

Could you please send me your design file for checking? I've tested the configuration with options from your pdf. The INT.OUT output provides pulses correctly. You can share design file to my email Pavlo.Zakalyk@diasemi.com to keep it confidential. Thanks.

Hi Pavlo,

Hi Pavlo,
many thanks for your test. I confirm that the signals are correct and as expected. Just checked with an oscilloscope. I suppose that looking at the LED indicators was misleading.
Many thanks for your time and qualified support.
