My AD9364 configurations are as below:
1. TDD mode (0x013=0x00)
2. To Alert = 1 (0x014=0x1D)
3. txnrx and Enable(level) by pin control. (0x015=08 or 0x0c)
After initial config done, the ENSM enter ALERT state. The reg 0x017=0x15. I set TXNRX = high, and then set ENABLE=high, the device enter TX state. The reg 0x017=16. And then set ENABLE=low, ENSM enter ALERT state,0x017=0x15.
But I set TXNRX=low, and then set ENABLE=high, ENSM cannot enter RX state, reg 0x017 is still 0x15. BOTH reg 0x015 =0x08 and 0x0c I have tried. It does not work.
Anyone can help me with this problem?
