Figure 10. Read Mode Sequences
Note: 1. The seven most significant bits of the Device Select Code of a Random Read (in the 1st and 3rd bytes) must be identical.
Read Operations
Read operations are performed independently of
whether hardware or software protection has been
set.
The device has an internal address counter which
is incremented each time a byte is read.
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
without sending a Stop condition.
Then, the bus master sends another Start condi-
tion, and repeats the Device Select Code, with the
RW bit set to 1. The device acknowledges this,
and outputs the contents of the addressed 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 RW bit set to 1. The de-
vice acknowledges this, and outputs the byte
addressed by the internal address counter. The
counter is then incremented. The bus master ter-
minates the transfer with a Stop condition, as
shown in Figure 10,
without acknowledging the
byte.
