MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow).

Detailed explanation-2: -BCD (Binary Coded Decimal) is simply the 4-bit binary code representation of a decimal digit. Each decimal digit replaced in the integer and fractional parts by its binary equivalent. BCD Code uses four bits to represent the 10 decimal digits of 0 to 9.

Detailed explanation-3: -BCD (binary-coded decimal), also called alphanumeric BCD, alphameric BCD, BCD Interchange Code, or BCDIC, is a family of representations of numerals, uppercase Latin letters, and some special and control characters as six-bit character codes.
