Due to an error in the firmware pin 9 of U123 is always configured as an output pin. This pin is directly connected to an output of the line driver IC U321. To prevent damage to the PIA chip it is recommended to remove the line driver U321. Since U321 is only needed for internal testing, it can be removed without any problem. | Due to an error in the firmware pin 9 of U123 is always configured as an output pin.
