RANDOM ADDRESS BYTE READ OPERATION

Using random read operations, the master can access any memory location at any time. Before it issues the

is performed in the following steps:

1. The master first issues a Start condition, the slave address, and the word address to be read. (This step sets

the internal word address pointer of the 24LC08 to the desired address.)

2. When the master receives an ACK for the word address, it immediately re-issues a start condition followed

3. The 24LC08 then sends an ACK and the 8-bit data stored at the desired address.

4. At this point, the master does not acknowledge the transmission, but generates a stop condition instead.

5. In response, the 24LC08 stops transmitting data and reverts to its stand-by mode

(see Figure 3-13).
