LoRa-E5 register settings for oscillators

I am developing a custom application for the LoRa-E5. I know there is a 32 MHz TCXO and 32 kHz oscillator built into the module. There are parameters, however, that must be set that depend directly on the specifications of the crystal and TCXO. Specifically, my questions:

  • What LSE drive level is required for the 32 kHz oscillator?
  • What are the correct parameters for the sub-GHz radio Set_TcxoMode() command?
  • What are the correct contents of the sub-GHz radio register SUBGHZ_HSEINTRIMR and SUBGHZ_HSEOUTTRIMR?
