Device operation
19/35
4.10
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’s internal address counter is
incremented by one, to point to the next byte address.
4.11
Random Address Read
A dummy Write is first performed to load the address into this address counter (as shown in
Figure 10
) but
without
sending a Stop condition. Then, the bus master sends another Start
condition, and repeats the Device Select Code, with the Read/Write bit (RW) set to 1. The
device acknowledges this, and outputs the contents of the addressed byte. The bus master
must
not
acknowledge the byte, and terminates the transfer with a Stop condition.
4.12
Current Address Read
For the Current Address Read operation, following a Start condition, the bus master only
sends a Device Select Code with the Read/Write bit (RW) set to 1. The device
acknowledges this, and outputs the byte addressed by the internal address counter. The
counter is then incremented. The bus master terminates the transfer with a Stop condition,
as shown in
Figure 10
,
without
acknowledging the Byte.
4.13
Sequential Read
This operation can be used after a Current Address Read or a Random Address Read. The
bus master
does
acknowledge the data byte output, and sends additional clock pulses so
that the device continues to output the next byte in sequence. To terminate the stream of
bytes, the bus master must
not
acknowledge the last byte, and
must
generate a Stop
condition, as shown in
Figure 10
.
The output data comes from consecutive addresses, with the internal address counter
automatically incremented after each byte output. After the last memory address, the
address counter ‘rolls-over’, and the device continues to output data from memory address
00h.
4.14
Acknowledge in Read mode
For all Read commands, the device waits, after each byte read, for an acknowledgment
during the 9
th
bit time. If the bus master does not drive Serial Data (SDA) Low during this
time, the device terminates the data transfer and switches to its Standby mode.
