Current Address Read operation, following a Start
condition, the bus master only sends a Device
Select Code with the RW bit 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 condition, as
shown in Figure 8, without acknowledging the
byte.
Sequential Read
This operation can be used after a Current
Address Read or a Random Address Read. The
bus master does acknowledge the data byte
Random Address Read
A dummy Write is performed to load the address
into the address counter (as shown in Figure 8) 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 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
The device has an internal address counter which
is incremented each time a byte is read. For the
