Instruction Reference Manual 39
Description
• JP (HL): The data in HL is loaded into the Program Counter. Thus the address of the next
instruction fetched is the data in HL.
• JP (IX): The data in index register IX is loaded into the Program Counter. Thus the address
of the next instruction fetched is the data in IX.
• JP (IY): The data in index register IY is loaded into the Program Counter. Thus the address
of the next instruction fetched is the data in IY.
• JP mn: The 16-bit constant mn is loaded into the Program Counter. Thus the address of the
next instruction fetched is mn. This instruction recognizes labels when used in the Dynamic C
assembler.
