*1: Data 0FFF is equivalent to 07FF as output data.
*2: Data 0800 is equivalent to 0000 as output data.
For PC system settings, select the cycle OUT refresh method for output
refreshing (DM 6639) as much as possible. If the user needs to select direct
OUT refresh method, take the following into consideration.
After executing an instruction, it takes approximately 0.5 ms for output com-
pletion. If a new instruction or the END instruction is executed within 0.5 ms,
the completion of the output of the previous instruction may delay.
When turning PC on or off, the output terminal may have voltage momentarily
(i.e., approximately 1 V for a few milliseconds). If this causes a problem, take
an appropriate countermeasure externally.
