POINT
(1) The SPBUSY instruction is used to read the execution status when using a
dedicated instruction. (Refer to Chapter 12.)
(2) More than one OUTPUT instruction cannot be executed simultaneously.
Execute the next OUTPUT instruction only after the execution of the first
OUTPUT instruction is completed.
