Hi,

To be sure we take into account everything we I would like to know.

- Mode of the MCU you use. (connection of the mode pins and value in MODE register)

- A value of the DDRK register.

- The method of the reading of the PTK.2,1. Is it measurement at the port pins or status of the PTK register or...

- Have you checked all writes to PORTK?

Best regards,

Ladislav
