... The SCL input is used to synchronize the data transfer to and from the device. 2.3 A0, A1, A2 The A0, A1 and A2 inputs are used by the 24VL024/ 24VL025 for multiple device operations. The levels on these inputs are compared with the corresponding bits in the slave address. The chip is selected if the compare is true ...

... The bus has to be controlled by a master device that generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24VL024/ 24VL025 works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated ...

... The master device must generate an extra clock pulse which is associated with this Acknowledge bit. Note: The 24VL024/24VL025 does not generate any Acknowledge bits if an internal programming cycle is in progress. The device that acknowledges has to pull down the ...

... The next three bits of the control byte are the Chip Select bits (A2, A1, A0). The Chip Select bits allow the use eight 24VL024/ 24VL025 devices on the same bus and are used to select which device is accessed. The Chip Select bits ...

... The device will acknowledge this control byte during the ninth clock pulse. The next byte transmitted by the master is the word address and will be written into the Address Pointer of the 24VL024/ 24VL025. After receiving ...

... 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 and ACK polling can be initiated immediately ...

... Upon receipt of the slave address with the R/W bit set to ‘1’, the 24VL024/24VL025 issues an acknowledge and transmits the 8-bit data word. The master will not acknowledge the transfer, but does generate a Stop condition and the 24VL024/24VL025 discontinues transmission (Figure 8-1) ...
