Appendix 4.2

(1) Definition
Hexadecimal (HEX) is a numeral system that represents four binary bits as one digit.
With four binary bits, sixteen different numeric values, 0 to 15, can be represented.
Hexadecimal notation uses 16 symbols to represent numeric values 0 to 15 in one digit, the symbols 0 to 9 to
represent values zero to nine, and A
higher digit (to the left) is incremented.
The following table lists the numeric representations in BIN, HEX, and DEC (decimal).
