... FUNCTIONAL DESCRIPTION The 24XX32AF supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, while a device receiving data is defined as a receiver. The bus has to be controlled by a master device which generates the Serial Clock (SCL), controls the bus access and gener- ates the Start and Stop conditions, while the 24XX32AF works as slave ...

... Control Chip Code Select Bits © 2009 Microchip Technology Inc. 24AA32AF/24LC32AF an Acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24XX32AF will select a read or write operation. FIGURE 5-1: Control Code Start Bit 5.1 Contiguous Addressing Across Multiple Devices ...

... WRITE OPERATIONS 6.1 Byte Write Following the Start condition from the master, the control code (4 bits), the Chip Select (3 bits), and the R/W bit (which is a logic low) are clocked onto the bus by the master transmitter. This indicates to the addressed slave receiver that the address high byte will follow once it has generated an Acknowledge bit during the ninth clock cycle ...

... ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a Write command has been issued from the master, the device initiates the internally-timed write cycle ...
