Figure 10. Read Mode Sequences
Note: 1. The seven most significant bits of the Device Select Code of a Random Read (in the 1
st
and 4
th
bytes) must be identical.
Read Operations
Read operations are performed independently of
the state of the Write Control (WC) signal.
After the successful completion of a Read opera-
tion, the device’s internal address counter is incre-
mented by one, to point to the next byte address.
Random Address Read
A dummy Write is first performed to load the ad-
dress into this address counter (as shown in
Fig-
ure 10.
) but withoutsending a Stop condition.
Then, the bus master sends another Start condi-
tion, and repeats the Device Select Code, with the
Read/Write bit (RW) set to 1. The device acknowl-
edges this, and outputs the contents of the ad-
dressed byte. The bus master must not
acknowledge the byte, and terminates the transfer
with a Stop condition.
Current Address Read
For the Current Address Read operation, following
a Start condition, the bus master only sends a De-
vice Select Code with the Read/Write bit (RW) set
to 1. The device acknowledges this, and outputs
the byte addressed by the internal address
counter. The counter is then incremented. The bus
master terminates the transfer with a Stop condi-
tion, as shown in
Figure 10.

ing the byte.
