I am trying to interface AD9914 in serial mode:
Function pin are set to 0001 as per datasheet, but when i am trying to read the chip for few registers I am getting all 1's and for few i am getting all 0's.
As per datasheet by default, assuming chip will be in 2 wire mode.
1. Giving master reset to the chip.
2. Sending RD command + 7 bit address followed by 32 clock cycles for read data.
Lets me know if I am missing any thing.
