Data is read from the control registers of the AD9883A in a similar
manner. Reading requires two data transfer operations:
The base address must be written with the R/
W
Bit of the slave
address byte low to set up a sequential read operation.
Reading (the R/
W
Bit of the slave address byte high) begins at
the previously established base address. The address of the read
register autoincrements after each byte is transferred.
To terminate a read/write sequence to the AD9883A, a stop
signal must be sent. A stop signal comprises a low-to-high tran-
sition of SDA while SCL is high.
A repeated start signal occurs when the master device driving
the serial interface generates a start signal without first generating
a stop signal to terminate the current communication. This is
used to change the mode of communication (read, write)
between the slave and master without releasing the serial
interface lines.
