Note: 1. This is preliminary data.
Current Address Read
The device has an internal address counter which
is incremented each time a byte is read. For the
Current Address Read mode, following a START
condition, the master sends a Device Select Code
with the RW bit set to ‘1’. The memory
acknowledges
addressed by the internal address counter. The
counter
terminates the transfer with a STOP condition, as
shown in Figure 8, without acknowledging the byte
output.
Sequential Read
This mode can be initiated with either a Current
Address Read or a Random Address Read. The
master does acknowledge the data byte output in
this case, and the memory continues to output the
next byte in sequence. To terminate the stream of
bytes, the master must not acknowledge the last
byte output, and must generate a STOP condition.
The
addresses, with the internal address counter
automatically incremented after each byte output.

After the last memory address, the address
counter ‘rolls-over’ and the memory continues to
output data from memory address 00h.
Acknowledge in Read Mode
In all read modes, the memory waits, after each
byte read, for an acknowledgment during the 9
bit time. If the master does not pull the SDA line
low during this time, the memory terminates the
data transfer and switches to its stand-by state.
