branching conditions are listed below.
Mnemonic Description Condition
BRA(BT) Always (true) Always
BRN(BF) Never (false) Never
BHI High C ∨ Z = 0
BLS Low or same C ∨ Z = 1
BCC(BHS) Carry clear
(high or same)
C = 0
BCS(BLO) Carry set (low) C = 1
BNE Not equal Z = 0
BEQ Equal Z = 1
BVC Overflow clear V = 0
BVS Overflow set V = 1
BPL Plus N = 0
BMI Minus N = 1
BGE Greater or equal N ⊕ V = 0
BLT Less than N ⊕ V = 1
BGT Greater than Z∨(N ⊕ V) = 0
BLE Less or equal Z∨(N ⊕ V) = 1
JMP  Branches unconditionally to a specified address.
BSR  Branches to a subroutine at a specified address.
JSR  Branches to a subroutine at a specified address.
RTS  Returns from a subroutine
Note: * Bcc is the general name for conditional branch instructions.
