Figure 33. I2C Read Procedure
READ PROCEDURE
(such as a microcontroller) needs to send the appropriate
control signals to the ADV3002 slave device. The signals are
controlled by the I2C master unless otherwise specified. For a
diagram of the procedure, see Figure 33. The steps for a read
procedure are as follows:
1. Send a start condition (while holding the I2C_SCL line
high and pulling the I2C_SDA line low).
2. Send the ADV3002 part address (seven bits). The upper five
bits of the ADV3002 part address are the static value [10010]
and the two LSBs are set by Input Pins I2C_ADDR[1:0].
This transfer should be MSB first.
3. Send the write indicator bit (0).
4. Wait for the ADV3002 to acknowledge the request.
5. Send the register address (eight bits) from which data is to
be read. This transfer should be MSB first.
6. Wait for the ADV3002 to acknowledge the request.
7. Send a repeated start condition (SR) by holding the
I2C_SCL line high and pulling the I2C_SDA line low.
8. Resend the ADV3002 part address (seven bits) from Step 2.
The upper five bits of the ADV3002 part address compose
the static value [10010]. The two LSBs are set by Input Pins
I2C_ADDR[1:0]. This transfer should be MSB first.
9. Send the read indicator bit (1).
10. Wait for the ADV3002 to acknowledge the request.
11. Read the data from the ADV3002. The ADV3002 serially
transfers the data (eight bits) held in the register indicated
by the address set in Step 5. This data is sent MSB first.
12. Do one of the following:
a. Send a no acknowledge (NACK) followed by a stop
condition (while holding the I2C_SCL line high and
pulling the SDA line high) and release control of the
bus to end the transaction (shown in Figure 33).
b. Send a no acknowledge (NACK) followed by a
repeated start condition (while holding the I2C_SCL
line high and pulling the I2C_SDA line low) and
continue from Step 2 of the write procedure (see the
previous Write Procedure section) to perform a write.
c. Send a no acknowledge (NACK) followed by a repeated
start condition (while holding the I2C_SCL line high
and pulling the I2C_SDA line low) and continue from
Step 2 of this procedure to perform a read from another
address.
d. Send a no acknowledge (NACK) followed by a repeated
start condition (while holding the I2C_SCL line high
and pulling the I2C_SDA line low) and continue from
Step 8 of this procedure to perform a read from the
next byte.
e. Send an acknowledge (ACK) and read the next byte of
data. Continue from Step 11.
13. Send a stop condition (while holding the I2C_SCL line
high and pulling the I2C_SDA line high).
