Hello, I want to communicate between the AD9959 eval board and the MCU. The configurations I made are as follows:
1) master reset
2) PWN DWN set
3) I write the value that activates all channels into the CSR register (240)
4) I select PLL Divider 20 from Func REG1 and set Above 255MHz
5) Since I work with Channel 1 from the CSR address, I activate it again (32)
6) I write my operating frequency to the CFTW0 address.
7) I write the amplitude of my sinus signal to the ACR address.
NOTE: During all writing operations, I set the IO Update pin to high - low positions and approximately 300us remains open.
SPI clock pol: 1 and clock phase: 1, SPI Speed: 500Khz
