Clock function CPU can read or write data including the year (last two digits), month, date, day, hour, minute, and second. Any (two-digit) year that is a multiple of 4 is treated as a leap year and calculated automatically as such until the year 2100. 2. Alarm function These devices have one alarm system that outputs interrupt signals from INT for PT7C4563 to CPU when the date, day of the week, hour, minute or second correspond to the setting. Each of them may output interrupt signal separately at a specified time. The alarm may be selectable between on and off for matching alarm or repeating alarm. 3. Programmable square wave output A square wave output enable bit controls square wave output at pin 7. 4 frequencies are selectable: 1, 32, 1.024k, and 32.768k Hz. 4. Interface with CPU Data is read and written via the I2C bus interface using two signal lines: SCL (clock) and SDA (data). Since the output of the I/O pin SDA is open drain, a pull-up resistor should be used on the circuit board if the CPU output I/O is also open drain. The SCL's maximum clock frequency is 400 kHz, which supports the I2C bus's high-speed mode. 5. Oscillator fail detect When oscillator fail, OSF bit will be set.

I2C Bus Interface a) Overview of I2C-BUS The I2C bus supports bi-directional communications via two signal lines: the SDA (data) line and SCL (clock) line. A combination of these two signals is used to transmit and receive communication start/stop signals, data signals, acknowledge signals, and so on. Both the SCL and SDA signals are held at high level whenever communications are not being performed. The starting and stopping of communications is controlled at the rising edge or falling edge of SDA while SCL is at high level. During data transfers, data changes that occur on the SDA line are performed while the SCL line is at low level, and on the receiving side the data is captured while the SCL line is at high level. In either case, the data is transferred via the SCL line at a rate of one bit per clock pulse. The I2C bus device does not include a chip select pin such as is found in ordinary logic devices. Instead of using a chip select pin, slave addresses are allocated to each device and the receiving device responds to communications only when its slave address matches the slave address in the received data. b) System Configuration All ports connected to the I2C bus must be either open drain or open collector ports in order to enable AND connections to multiple devices. SCL and SDA are both connected to the VDD line via a pull-up resistance. Consequently, SCL and SDA are both held at high level when the bus is released (when communication is not being performed). Vcc RP RP SDA SCL Master MCU Slave RTC Other Peripheral Device Note: When there is only one master, the MCU is ready for driving SCL to "H" and R P of SCL may not required.

Since the required status is the same as for the START condition, the SDA level changes from high to low while SCL is at high level. d) Data Transfers and Acknowledge Responses during I2C-BUS Communication  Data transfers Data transfers are performed in 8-bit (1 byte) units once the START condition has occurred. There is no limit on the amount (bytes) of data that are transferred between the START condition and STOP condition. The address auto increment function operates during both write and read operations. Updating of data on the transmitter (transmitting side)'s SDA line is performed while the SCL line is at low level. The receiver (receiving side) captures data while the SCL line is at high level. *Note with caution that if the SDA data is changed while the SCL line is at high level, it will be treated as a START, RESTART, or STOP condition. All trademarks are property of their respective owners. 2016-10-0003 www.diodes.com 13 11/10/2016 PT0333-5 PT7C4563  Data acknowledge response (ACK signal) When transferring data, the receiver generates a confirmation response (ACK signal, low active) each time an 8-bit data segment is received. If there is no ACK signal from the receiver, it indicates that normal communication has not been established. (This does not include instances where the master device intentionally does not generate an ACK signal.) Immediately after the falling edge of the clock pulse corresponding to the 8th bit of data on the SCL line, the transmitter releases the SDA line and the receiver sets the SDA line to low (= acknowledge) level. SCL from Master 8 2 1 9 SDA from transmitter (sending side) Release SDA Low active SDA from receiver (receiving side) ACK signal After transmitting the ACK signal, if the Master remains the receiver for transfer of the next byte, the SDA is released at the falling edge of the clock corresponding to the 9th bit of data on the SCL line. Data transfer resumes when the Master becomes the transmitter. When the Master is the receiver, if the Master does not send an ACK signal in response to the last byte sent from the slave, that indicates to the transmitter that data transfer has ended. At that point, the transmitter continues to release the SDA and awaits a STOP condition from the Master. e) Slave Address The I2C bus device does not include a chip select pin such as is found in ordinary logic devices. Instead of using a chip select pin, slave addresses are allocated to each device. All communications begin with transmitting the [START condition] + [slave address (+ R/W specification)]. The receiving device responds to this communication only when the specified slave address it has received matches its own slave address. Slave addresses have a fixed length of 7 bits. See table for the details. An R/W bit is added to each 7-bit slave address during 8-bit transfers. Operation Read Write 2.
