diagramas.diagramasde.comBCD Binary-Coded Decimal (BCD) are decimal numbers where each digit is represented by a four-bit binary number. BCD is commonly used with input and output devices. A thumbwheel switch is one example of an input device that uses BCD. The binary numbers are broken into groups of four bits, each group representing a decimal equivalent.
Number Representation and Computer Arithmetic
web.ece.ucsb.eduOne way to encode decimal digits using binary signals is to encode each of the digits 0-9 by means of its 4-bit binary representation. The resulting binary-coded decimal (BCD) representation is shown below:
PCF8523 Real-Time Clock (RTC) and calendar
www.nxp.comcoded in Binary Coded Decimal (BCD) format. Other registers are either bit-wise or standard binary. When one of the RTC registers is read, the contents of all counters are frozen. Therefore, faulty reading of the clock and calendar during a carry condition is prevented. The PCF8523 has a battery backup input pin and battery switch-over circuit.

www.nxp.comalarm registers are all coded in Binary Coded Decimal (BCD) format. When one of the RTC registers is written or read, the contents of all time counters are frozen. Therefore, faulty writing or reading of the clock and calendar during a carry condition is prevented. For details on maximum access time, see Section 8.4 on page 25. Fig 5.
