2.3" 16 segment common anode LEDs, HT16K33 and ULN2803 (now common cathode)

HKJ-lygte:
ROW pins pull high when active and high impedance when passive...

COM pins pull low when active and is high impedance when passive...

Can you please tell us where this is explained in the data sheet?

These are the diagrams from the data sheet that show how the outputs are wired internally:

Looks like COM 0-3 are different from COM 4-7.
