INTERFACING EXAMPLES
The SPI interface of the AD5501 is designed to allow it to be easily
connected to industry-standard DSPs and microcontrollers.
Figure 18 shows how the AD5501 can be connected to the Analog
Devices, Inc., Blackfin DSP. The Blackfin has an integrated SPI
port that can be connected directly to the SPI pins of the AD5501.
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.

Figure 18. Interfacing to a Blackfin DSP
The Analog Devices ADSP-21065L is a floating point DSP with
two serial ports (SPORTs). Figure 19 shows how one SPORT
can be used to control the AD5501. 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
AD5501 by writing to the transmit register. When a read operation
is performed, the data is clocked out of the AD5501 on the last
12 SCLKs. The DSP receive interrupt can be used to indicate when
the read operation is complete.
