Figure 9. Read Mode Sequences
Note: 1. The seven most significant bits of the Device Select Code of a Random Read (in the 1st and 4th 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
without sending a Stop condition. Then,
the bus master sends another Start condition, and
repeats the Device Select Code, with the RW bit
set to 1. The device acknowledges this, and out-
puts the contents of the addressed byte. The bus
master must
not acknowledge the byte, and termi-
nates 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 9,
without acknowledging the
byte.
