... 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 24VL014H 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 24VL014H 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 24VL014H does not generate any Acknowledge programming cycle is in progress. The device that acknowledges has to pull down the ...

... Start condition from the master device (Figure 5-1). The control byte consists of a four-bit control code; for the 24VL014H this is set as ‘1010’ binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0). The Chip Select ...

... Page Write The write-control byte, word address and the first data byte are transmitted to the 24VL014H in the same way byte write. But instead of generating a Stop condition, the master transmits additional data bytes to the 24VL014H that are temporarily stored in ...
Page 10
... 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 ...

... Sequential Read Sequential reads are initiated in the same way as a random read except that after the 24VL014H transmits the first data byte, the master issues an acknowledge as opposed to a Stop condition in a random read. This directs the 24VL014H to transmit the next sequentially addressed 8-bit word (Figure 8-3) ...
