Jumps to 16bit registers
Although the instruction JP (HL)
looks like it's using indirect addressing, it doesn't.
It takes the address in HL
as the new PC
, so it should be read as if it's
JP HL
.
The same applies for JP (IX)
and JP (IY)
- the actual register is used not the value at that address.
Flags Affected
