# BNEQ

(Redirected from BNZE)

Instruction Name | Branch If Not Equal Branch If Not Zero |

Mnemonics | BNEQ/BNZE |

CP1610 Clock Cycles | 7 or 9 |

Interruptible | Yes |

Opcode Range | $020C, $022C |

The Branch If Not Equal opcode (BNEQ) is a two-decle opcode that is a part of the Branch family of opcodes. It is also known by the name Branch If Not ZEro (BNZE) because a test for inequality is functionally equivalent to a test for a non-zero result. Essentially, to test inequality, the CMP type of operations subtract operand #2 from operand #1 and if the result is non-zero, then the operands must not be equal. This instruction causes the CP1610 to branch if the Zero Flag is clear to the address specified by the following parameters.

Format - Decle #1 Format - Word #2 (All 16 bits are significant) 0000:0010:00d0:1100 aaaa:aaaa:aaaa:aaaa

where:

d indicates the direction of the branch such that: d == 0 indicates to branch in the forward direction d == 1 indicates to branch in the reverse direction

aaaaaaaaaaaaaaaa indicates the amount of offset
