Description ANDW(034) takes the logical AND of data specified in I
1
and I
2
and outputs
the result to R.
• The logical AND is taken of corresponding bits in I
1
and I
2
in succession.
• When the content of corresponding bits in both I
1
and I
2
are 1 or when
either is 0, a 0 will be output to the corresponding bit in R.

Flags
Precautions 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.
