LORA E5 internal GPIO for RF SW control

Hi,
+1 to this. CubeMX asks me to set these 3 GPIOs and in the product page there´s not enough information:

Info on the Lora E5 page:

  • LSE
    • 32.768KHz crystal oscillator
  • RF Switch
    • Receive: PA4=1, PB5=0
    • Transmit(high output power, SMPS mode): PA4=0, PB5=1

Thanks in advance!
