Read operations

Read operations are performed independently of the state of the Write Control (WC) signal.

After the successful completion of a Read operation, the device internal address counter is

incremented by one, to point to the next byte address.

4.2.1

Random Address Read

The Random Address Read is a sequence composed of a truncated Write sequence (to

define a new address pointer value, see Table 3) followed by a current Read.

The Random Address Read sequence is therefore the sum of [Start + Device Select code

with RW=0 + two address bytes] (without Stop condition, as shown in Figure 8)] and [Start

condition + Device Select code with RW=1]. The memory device acknowledges the

sequence and then outputs the contents of the addressed byte. To terminate the data

transfer, the bus master does not acknowledge the last data byte and then issues a Stop

condition.
