Cannot run at -20 degree C for Murata CMWX1ZZABZ-078 Lora module and I-CUBE-LRWAN firmware.

Hi,We are using Murata CMWX1ZZABZ-078 Lora module and I-CUBE-LRWAN firmware for our IOT project development. There is another host ( STM32) MCU sending AT command at 115200 baud rate to control murata lora module and it works fine at room temperature...

I purchased the STUSB4500QTR and actually operated it. After assembling the electronic board, I dumped the default contents of the register and it became as shown in [1A] below. Next, when I purchased parts from a new lot during mass production and assemb
