SERIAL CONTROL INTERFACE
7.
Send the data (eight bits) to be written to the register
whose address was set in Step 5. This transfer should be
MSB first.
RESET
On initial power-up, or at any point during operation, the
AD8192 register set can be restored to the default values by
pulling the RESET pin to low according to the specification in
During normal operation, however, the
RESET pin
must be pulled up to 3.3 V.
8.
Wait for the AD8192 to acknowledge the request.
9.
Do one of the following:
a.
Send a stop condition (while holding the I2C_SCL
line high, pull the I2C_SDA line high) and release
control of the bus to end the transaction (shown in
WRITE PROCEDURE
To write data to the AD8192 register set, an I2C master (such as
a microcontroller) needs to send the appropriate control signals
to the AD8192 slave device. The signals are controlled by the
I2C master unless otherwise specified. For a diagram of the
procedure, see Figure 28. The steps for a write procedure are as
follows:
b.
Send a repeated start condition (while holding the
I2C_SCL line high, pull the I2C_SDA line low) and
continue with Step 2 in this procedure to perform
another write.
c.
Send a repeated start condition (while holding the
I2C_SCL line high, pull the I2C_SDA line low) and
continue with Step 2 of the read procedure (in the
Read Procedure section) to perform a read from
another address.
1.
Send a start condition (while holding the I2C_SCL line
high, pull the I2C_SDA line low).
2.
Send the AD8192 part address (seven bits). The upper six
bits of the AD8192 part address are the static value [100100]
and the LSB is set by Input Pin I2C_ADDR. This transfer
should be MSB first.
d.
Send a repeated start condition (while holding the
I2C_SCL line high, pull the I2C_SDA line low) and
continue with Step 8 of the read procedure (in the
Read Procedure section) to perform a read from the
same address set in Step 5.
3.
Send the write indicator bit (0).
4.
Wait for the AD8192 to acknowledge the request.
5.
Send the register address (eight bits) to which data is to be
written. This transfer should be MSB first.
6.
Wait for the AD8192 to acknowledge the request.
