Figure 9. 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 9.
) but withoutsending a Stop condition. Then,
the bus master sends another Start condition, and
repeats the Device Select Code, with the Read/
Write bit (RW) set to 1. The device acknowledges
this, and outputs the contents of the addressed
byte. The bus master must notacknowledge the
byte, and terminates the transfer with a Stop con-
dition.
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 9.
, withoutacknowledging
the byte.
