Hello all,  
When I debugged my LimeSDR-mini board, found the port mode selection settings of LimeLight &PAD tab on GUI is not consistent with corresponding registers’ values. When I selected LimeLight port 1 &2 TRXIQ and set the port1 &2 selection to TXIQ, pls refer to the following screemshot.

 ![LimeLight%20Settings](https://canada1.discourse-cdn.com/flex034/uploads/myriadrf/original/2X/c/ca54d0aa44637d8fce5b50f25c6ceab9a1094642.jpeg)

Then I save the GUI settings as a ini file, found the corresponding register bit 0x0023 [4] and 0x0023 [1] are 1s, if these bits are 1s, it proves that they worked in RXIQ mode, in fact, we chose the TXIQ mode. Meanwhile, If I choose RXIQ mode on GUI, the corresponding register bit 0x0023 [4] and 0x0023 [1] are 0s, very strange.

 ![register_0x0023](https://canada1.discourse-cdn.com/flex034/uploads/myriadrf/original/2X/5/5196762c8964f293407e4a6c19f55533a541b1c2.jpeg)  
I think this should be a bug.

Could you pls help me to check it and give me a response? Thanks!

Indeed the GUI value names don’t match what is in register description.

@Zack Can you confirm if the register description is correct and GUI needs fixing?
