the Device Select Code, with the RW
bit set to ‘1’.
The memory acknowledges this, and outputs the
contents of the addressed byte. The master must
not
acknowledge the byte output, 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
Current Address Read mode, following a START
condition, the master sends a Device Select Code
with the RW bit set to ‘1’. The memory acknowl-
edges this, and outputs the byte addressed by the
internal address counter. The counter is then in-
minated the internal write cycle, it responds with
an Ack, indicating that the memory is ready to
receive the second part of the next instruction
(the first byte of this instruction having been sent
during Step 1).
Read Operations
Read operations are performed independently of
the state of the WC pin.
Random Address Read
A dummy write is performed to load the address
into the address counter, as shown in Figure 8.
Then,
without
sending a STOP condition, the mas-
ter sends another START condition, and repeats
Figure 8. Read Mode Sequences
Note: 1. The seven most significant bits of the Device Select Code of a Random Read (in the 1
st
and 4
th
bytes) must be identical.
