INTERFACING EXAMPLES
The SPI interface of the AD5504 is designed to allow it to be
easily connected to industry-standard DSPs and microcon-
trollers. Figure 19 shows how the AD5504 can be connected to
the Analog Devices, Inc., Black fin ® DSP. The Black fin has an
integrated SPI port that can be connected directly to the SPI
pins of the AD5504. Programmable input/output pins are also
available and can be used to read or set the state of the digital
input or output pins associated with the interface.

two serial ports (SPORTs). Figure 20 shows how one SPORT
can be used to control the AD5504. In this example, the transmit
frame synchronization (TFS) pin is connected to the receive
frame synchronization (RFS) pin. The transmit and receive
clocks (TCLK and RCLK) are also connected together. The user
can write to the AD5504 by writing to the transmit register. When a
read operation is performed, the data is clocked out of the AD5504
on the last 12 SCLKs. The DSP receive interrupt can be used to
indicate when the read operation is complete.
