Basic I/O Unit Instructions Section 3-23
When the input condition is met, self maintenance is performed by output A
and IOWR(223) is executed with each cycle until the Equals Flag turns ON.
When the writing is completed and the Equals Flag turns ON, output B turns
ON and the self maintenance is cleared.
Be sure to place condition flags directly after IOWR(223) 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.
Example In this example, IOWR(223) is used to write data.
