I'd like to control external PA, LNA and antenna switch from GPIOs of ADF7030-1, but I cannot find descriptions in GIPO sections in UG1002 software reference manual. Would you tell me the following detail about them?
* Available GPIOs for these purpose.
*For PA, LNA control:
Signal logic (output value in TX/RX, Timing)
Control method (Are they automatically set due to TX/RX state?)
*Antenna switch control (2bits required):
How to configure GPIOs and their output values?
Control method (Are they automatically set due to TX/RX state or manually set?)
For external PA, LNA or antenna switch control, there are 6 available gpio pins you use: GPIO0, GPIO1, ... GPIO5. The functions to configure, set or clear the gpio pins are available in the device drivers and are provided below:
The gpio pins are set and cleared manually.
