The AD9838 has no SDO pin, so it is not possible to read back registers.
You can perform an easy proof of life enabling the SIGN BIT OUT. The pin should go low when the corresponding bit is enabled in the register.
If you need a wider set of functions to configure the chip, you may use the No-OS driver provided on Github: github.com/.../ad9833
