Be sure to place condition flags directly after IORD(222) instructions, and not
after any other instructions. If a condition flag is placed after another instruc-
tion, it will be affected by the execution results of that instruction.
In this example, IORD(222) is used to read data.
When CIO 0.00 is turned ON, 10 words are read from the Special I/O
Unit with unit number 3, and are stored in D100 to D109.

The control code (C) varies depending on the Special I/O Unit.
Special I/O Unit (Unit #3)
Outputs the contents of the CPU Unit's I/O memory area to a Special I/O Unit
or CPU Bus Unit.
This instruction can be used in the CP1H CPU Units only. It cannot be used in
the CP1L CPU Units. If IOWR(223) is used in a CP1L CPU Unit, Error Flag
(ER) will be turned ON.
