Writing completion (W1)
W1=0: "W1" is usually reset. The "W1=0" indicates that the
"WINDW" is not executed or the "WINDW" being executed
now.
W1=1: "W1" is set when the writing a data is completed by the
writing command (ACT=1). As soon as writing a data is
completed (W1=1), reset "ACT" (ACT=0).
Operation output register
If an error occurs during execution of the "WINDR" or "WINDW", the
bit in the operation output register is set. At the same time, the writing
completion is set (W1=1). Details of the error are output to the
completion code (CTL+2) in the control data area. See Chapter 5.

Notes when this functional instruction is used in subroutine
When you use the function of a low-speed response, there are a few
limitations. See Subsection 1.4.4.3. When you use the function of a
high-speed response, there is no limitation.
