6.2. Three-Character Encoding
This encoding technique is applied to express data having maximum length of 18 bits. Encoding is done
by separating data into upper, middle and lower 6 bits and then 30H is added to convert them into ASCII
characters. Figure 4 and 5 shows the Three-Character encoding and decoding example.
