Teensy 4.1, pulldown 10K resistor on pin G10 (AD_B0_11)

Hi there, I'm new to the forum
I'm learning about the Teensy board (software and hardware) and reading the documentations I wasn't able to find the purpose of the 100K resistor pulldown connected to pin G10 and K3 (AD_B0_11, DCDC_PSWITCH).
It is clear to me the presence of the resistor to the pin K3 (DCDC_PSWITCH): to keep the DCDC converter pin LOW during the power-on sequence until the MKL02Z32 rise the pin and reset the MCU,


My question is related to the pin G10 (AD_B0_11), why this pin is connected together with K3 (DCDC_PSWITCH)?
If I'm not wrong pin G10 (AD_B0_11) is an I/O pin without other specific function.

Can someone give some indications?

Thank you very much !

I think it does have a specific function: JTAG TRST.
