AWR1642: How to trigger warm reset on pin N9 in AWR1642?

Hi:

    I‘ve read AWR1642 Referece Manual, I found Ihave to write config to MISCCTL1 register to enable warm reset trigger from outside. But I found this register is not mentioned in 'reg_toprcm_xwr16xx.h'. Is there actually a register named this, and is there any way I can config this register in SDK, or I have to write this register on my own in SDK? Thank you!
