|Instruction Name||Branch If Not Equal|
Branch If Not Zero
|CP1610 Clock Cycles||7 or 9|
|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
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
