using Index Registers
ANDW(034) takes the logical AND of data specified in I
the result to R.
• The logical AND is taken of corresponding bits in I
• When the content of corresponding bits in both I
either is 0, a 0 will be output to the corresponding bit in R.

When ANDW(034) is executed, the Error Flag will turn OFF.
If as a result of the AND, the content of R is 0000 hex, the Equals Flag will
turn ON.
If as a result of the AND, the leftmost bit of R is 1, the Negative Flag will turn
ON.
Takes the logical AND of corresponding bits in double words of word data and/
or constants.
