BMI (Branch Minus) is a Super FX instruction that performs a conditional jump if the sign flag is set. If the sign flag is clear, control simply falls through. The instruction after BMI is already in the pipeline and will run even if the branch occurs.

No flags are affected.

Syntax

BMI e

where e can be from -128 to 127.

Example

Let the sign flag be set. This instruction jumps the program forward 5 bytes:

 BMI $+5h
