I'm a student and I'm working on my first project with a DDS. My project consists in making the communication between the DDS and a MBED controller via SPI. The pins I have been using to try it are:
AT THE U5 IO HEADER:
AT THE U6 IO HEADER:
AT THE U9 IO HEADER:
About the IO_UPDATE and the EXT_PWR_DWN I didn't understand their behavior. Can Someone help me?
Thanks for the attention,
