AD9985
Data is read from the control registers of the AD9985 in a
similar manner. Reading requires two data transfer operations:
Rev. 0 | Page 27 of 32
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 AD9985, a stop signal
must be sent. A stop signal comprises a low-to-high transition
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 communi-
cation. This is used to change the mode of communication
(read, write) between the slave and master without releasing the
serial interface lines.
