Individual output bits can be output in byte units.
When the number of output points of the device is 4, the individual output bits are arranged as shown
below and byte data to be output is a value between 0 and 15.
Ex. Output of bit 7 (ON), bit 6 (OFF), bit 5 (ON), bit 4 (OFF), bit3 (ON), bit 2 (OFF), bit 1 (ON)
and bit 0 (OFF)
Byte data = 170 (AAH)
