Cum realizez interfata de la un controler pt afisaj 8279 la un 6 led-uri cu 14 segmente?

Stiu ca atunci cand am un led cu 7 segmente,conectez iesirea porturilor Out A0-Out A3,Out B0-Out B3 la intrarile in led.

Iesirile SL0-SL3 le folosesc pt a selecta unul dintre leduri.


Daca am doar 8 porturi de iesire (Out A0-Out A3, Out B0-Out B3) cum le pot conecta la intrarile de la un led cu 14 segmente?




Mentionez ca am consultat datasheet-ul.
