LJMP (Long Jump) is a Super FX instruction that performs a (possibly interbank) jump.
The low byte of the source register is loaded into the program bank register.
According to fullsnes, the official documentation has the bank and offs operands for LJMP mixed up. [2]
The operand can be any register from R8 to R13.
The instruction following LJMP is already in the pipeline (the delay slot) and will be executed before the first instruction at the jump target.
