Mnemonics Quickview

Die Angaben in der Tabelle beziehen sich auf die Schreibweise im Editor und haben nichts mit der realen Speicherung während der Ausführung gemeinsam!! Wir schreiben bekanntlich $C100, im Speicher wird eine Adresse aber LSB/MSB, also $00, $C1, abgelegt.

#$nn  = Zahl für unmittelbare Adressierung
$ll   = Zero-Page Adresse
$hhll = 16-Bit-Adresse
