by

1 Answer

Answer :

LDA  copies  the  data  byte  into  accumulator  from  the  memory  location  specified by the 16-bit address. STA copies the data byte from theaccumulator in  the  memory  location  specified  by  16-bit  address.  DAA  changes  the  contents  of  the accumulator from binary to 4-bit BCD digits.
