Some websites like:
- https://clrhome.org/table/#or%20ixh
- http://www.z80.info/z80undoc.htm

I also tried Visual Studio Code extensions like Z80 Assembly Meter and Z80 Instruction Set and they show the same result as another assembler:

OR IYH -> FDB4
OR IYL -> FDB5

But it seems z80asm does the opposite. Note the issue may be also the same for AND, XOR and IX part.
