I can see in my design strange behavior linked to the profiles configuration on AD9913.The component configuration is:
16MHz input multiplied by 15 = 240MHz, switching mode, serial configuration (SPI 200kbps)
The issue is:
I configure profiles 0,1,2 following steps below:
Config of profile 0
Config of profile 1
RD check profile 1
Config of profile 2
RD check profile 2
I systematically read profile0 configuration in profile 1 and 2 registers even if:
- I program profiles 0, 1, 2 with different values
- OR I just program profile 0
I have not checked content of other profiles.
RD check is done on oscilloscope, adresses are correct. I program successfully CFR1 and CFR2.
MANY THANKS for feedback....
