CC1310: VDDS voltage level & POR trigger

Part Number:CC1310

Dear lprf team,

I understand from the following post : https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/635782 that when VDDS goes below 1.8v - 50 mV ie 1.75v then a POR is triggered based on a 16mV hysteresis scheme

Q1 : Is this right? are these voltage levels specified in a TI official document (datasheet, …)? If not, why?

Q2 : At what voltage level a POR is triggered when enabling the brown out detector on VDDS?

Thank you!

Best regards,

Guillaume
