I am dealing with EFR32FG14 Flex Gecko Kit and trying to set my custom filter for TX output. I set "Custom PSK" in shaping filter input in Simplicity Studio and got no idea where can I write my filter taps.
Is it possible to do it?
I'm afraid this parameter can not configure by radio configurator currently.
For more information please refer to AN971
We never provide document about radio registers.
What is your use case? Which part you are not satisfy your requirement?

I am migrating from si4463 to EFR32FG14 series. My product operates on 9600bps and 2GFSK modulation and needs to be shape filtered with custom filter on output. I designed such filter for si4463, which has 17 registers for both TX / RX filters taps. So, this is only the thing I miss in your SoC. That is why I need your help!
EFR32 does not have its registers exposed. You can only use the radio configurator and RAIL to change the behavior of the radio.This means that there is no interface for creating a custom Tx shaping filter in the tool chain, you can only select the ones that are listed on the configurator GUI. This is indeed different to our Si446x toolchain approach. Sorry.
