^*1System status register (D9008) in the data register has an area for 2 words. When accessing D9008 on the Display, you need to access separately both from the upper and lower words.

e.g. When accessing the 16th bit, assign "D9008,00" on the Display. In the same way, when accessing the 0 bit, assign "D9009,00".

^*2Once a bit is written, the Display reads the corresponding word address of the External Device, sets the bit to the read-in word address, and returns it to the External Device. While the Display reads data of the External Device and returns the data, if the writing process is conducted with the word address ladder program, data may not be written correctly.
