Read operations

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

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

For the Read instructions, after each byte read (data out), the device waits for an

acknowledgment (data in) during the 9th bit time. If the bus master does not acknowledge

during this 9th time, the device terminates the data transfer and switches to its Standby

mode.

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.

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

with R/W=0 + address byte] (without Stop condition, as shown in Figure 7) and [Start

condition + Device Select code with R/W=1]. The memory device acknowledges the

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