 How to Use Bits
Refer below for how to turn on the bits (in case the last digit of the set value is H).
Set the value of hexadecimal number transformed from the binary number.
■ Binary number
In the Binary number system, the figure is expressed using two (0 and 1) numerical
characters. The figure increases from “0”, and then “1” and moves on to the next digit to
“10”, “11”, etc.

■ Hexadecimal number
In the Hexadecimal number system, the figure is expressed using nine numerical characters
(from 0 to 9) and alphabetical characters (from A to F). The figure is gradually increased
from “0” to “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “A”, “B”, “C”, “D”, “E”, “F” and then moves on
to the next digit to “10”, “11”, etc.
