    Hi,

    I found out that if KEY[1] and KEY[0] having the same clock pulse (80ns) means being pressed and released together, HEX0 will only show 0 (1000000) but not show 7 (1111000) check image.

    If KEY[1] and KEY[0] having different clock pulse (80ns and 120ns), HEX0 will show both 0 (1000000) and 7 (1111000) check image.

    Thanks,

    Best Regards,

    Sheng
