Characteristics subject to change without notice ACKNOWLEDGE After a successful data transfer, each receiving device is required to generate an acknowledge. The acknowledging device pulls down the SDA line during the ninth clock cycle, signaling that it received the 8 bits of data. The CAT1024/25 responds with an acknowledge after receiving a START condition and its slave address. If the device has been selected along with a write operation, it responds with an acknowledge after receiving each 8-bit byte. When the CAT1024/25 begins a READ mode it transmits 8 bits of data, releases the SDA line and monitors the line for an acknowledge. Once it receives this acknowledge, the CAT1024/25 will continue to transmit data. If no acknowledge is sent by the Master, the device terminates data transmis– sion and waits for a STOP condition. WRITE OPERATIONS Byte Write In the Byte Write mode, the Master device sends the START condition and the slave address information (with the R/W ¯¯ bit set to zero) to the Slave device. After the Slave generates an acknowledge, the Master sends a 8-bit address that is to be written into the address pointers of the device. After receiving another acknow- ledge from the Slave, the Master device transmits the data to be written into the addressed memory location. The CAT1024/25 acknowledges once more and the Master generates the STOP condition. At this time, the device begins an internal programming cycle to non- volatile memory. While the cycle is in progress, the device will not respond to any request from the Master device. Figure 5. Start/Stop Timing Figure 6.
