RANDOM ADDRESS BYTE READ OPERATION
Using random read operations, the master can access any memory location at any time. Before it issues the
slave address with the R/
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
2. When the master receives an ACK for the word address, it immediately re-issues a start condition followed
3. The 24LLC16 then sends an ACK and the 8-bit data stored at the pointed address.
4. At this point, the master does not acknowledge the transmission, generating a stop condition.
5. The 24LLC16 stops transmitting data and reverts to stand-by mode (see Figure 5-13).
