Often used in conjunction with TST or CMP. BEQ can also be thought of as “branch if equal”, since for example CMP.L D0,D1 will set Z if both are equal, thus causing a subsequent BEQ to branch. BNE Branch if not equal (Z unset). Inverse of BEQ. BMI Branch if minus (N set). BPL Branch if positive (N unset). haleigh groulx
