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
/
W
bit set to “1”, the master must first perform a “dummy” write operation. This operation
is performed in the following steps:
1. The master first issues a start condition, the slave address, and the word address (the first and the second
addresses) to be read. (This step sets the internal word address pointer of the S524AD0XD1/D0XF1 to the
desired address.)
2. When the master receives an ACK for the word address, it immediately re-issues a start condition followed
by another slave address, with the R
/
W
bit set to “1”.
3. The S524AD0XD1/D0XF1 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 S524AD0XD1/D0XF1 stops transmitting data and reverts to stand-by mode (see Figure 8-14).
