6.3. Four-Character Encoding
This encoding technique is applied to express data having maximum length of 24 bits. Encoding is done
by separating data into four parts of 6 bits each and then 30H is added to convert them into ASCII characters.
Figure 6 and 7 shows the Four-Character encoding and decoding example.
