Questions answered in Z80 manuals
What does the OUTD instruction do?
OUTD transfers a byte from the memory location pointed to by HL to an I/O port selected by register C, then decrements B and HL.
How many T‑states does the OTDR instruction take at 4 MHz?
At 4 MHz, OTDR requires 5.25 T‑states per execution when B ≠ 0, and 4 T‑states when B = 0.
