Read Operations
Read operations are independent of the state of the
MODE pin. On delivery, the memory content is set
at all "1’s" (or FFh).
Current Address Read.
The memory has an inter-
nal byte address counter. Each time a byte is read,
this counter is incremented. For the Current Ad-
dress Read mode, following a START condition,
the master sends a memory address with the RW
bit set to ’1’. The memory acknowledges this and
outputs the byte addressed by the internal byte
address counter. This counter is then incremented.
The master does NOT acknowledge the byte out-
put, but terminates the transfer with a STOP con-
dition.
Random Address Read.
A dummy write is per-
formed to load the address into the address counter
(see Figure 11). This is followed by another START
condition from the master and the byte address is
repeated with the RW bit set to ’1’. The memory
acknowledges this and outputs the byte ad-
dressed. The master have to NOT acknowledge
the byte output, but terminates the transfer with a
STOP condition.
Sequential Read.
This mode can be initiated with
either a Current Address Read or a Random Ad-
dress Read. However, in this case the master
DOES acknowledge the data byte output and the
memory continues to output the next byte in se-
quence. To terminate the stream of bytes, the
