JP

Absolute jumps to the address. Can be conditional or unconditional. JP takes one more byte than JR, but is also slightly faster, so decide whether speed or size is more important before choosing JP or JR. JP (HL), JP (IX), and JP (IY) are unconditional and are the fastest jumps, and do not take more bytes than other jumps.
