<DIV><FONT face=Arial size=2>OE - output enable uvolnuje vystupne budice na
zbernicu, to by malo byt iba pri citani. Takze priamo(alebo nepriamo) na
signal RD.</FONT></DIV>
<DIV><FONT face=Arial size=2>CE - chip enable, spravidla na nejaky adresny
dekoder alebo riadiaci signal alebo stale aktivovany (zvysuje to
spotrebu).</FONT></DIV>
<DIV><FONT face=Arial size=2>CE musi byt aktivovany aj pri
zapise!!!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Takze spojit CE a OE v beznom pripade nie je dobre
riesenie...na zbernici bude v dobe zapisu viac ako jeden budic...</FONT></DIV>
