The Branch if Less Than or Equal opcode (BLE) is a two-decle opcode that is a part of the [[Branch]] family of opcodes. This instruction causes the [[CP1610]] to branch if the <strong>either</strong> the [[Zero Flag]] is set <strong>or</strong> the [[Sign Flag]] is not equal to the [[Overflow Flag]]. If this condition is true, then the [[CP1610]] branches to the address specified by the following parameters.<br/>

Format - Decle #1 Format - Word #2 (Unknown if all 16 bits are significant)

where:<br/>
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<br/>
aaaaaaaaaaaaaaaa indicates the amount of offset

See the [[Branch]] opcode family documentation for more information.
