CHAPTER 4: INSTRUCTION SET
AND %r,[%ir]
AND %r,[%ir]+ Logical AND of location [ir reg.] and r reg. and increment ir reg. 1 cycle
Function: r ← r ∧ [ir], ir ← ir + 1
Performs a logical AND operation of the content of the data memory addressed by the ir
register (X or Y) and the content of the r register (A or B), and stores the result in the r register.
Then increments the ir register (X or Y). The flags change due to the operation result of the r
register and the increment result of the ir register does not affect the flags.
Code:
