S

N ⊕ V, for signed tests.

V

0

Cleared.

N

R7

Set if MSB of the result is set; cleared otherwise.

Z

R7 ∧ R6 ∧ R5 ∧ R4 ∧ R3 ∧ R2 ∧ R1 ∧ R0

Set if the result is 0x00; cleared otherwise.

R (Result) equals Rd after the operation.

Example:

      and   r2,r3     ; Bitwise and r2 and r3, result in r2
      ldi   r16,1     ; Set bitmask 0000 0001 in r16
      and   r2,r16    ; Isolate bit 0 in r2
