TPS650861: PORESET management with "OTP Generator for LS1043A Rev.B"

Part Number:TPS650861

Hello,
We plan to use the TPS650861 PMIC to supply a LS1043A processor.

On the TI website, we have found some litterature which directly focus our need :
 - TPS65086100 User's Guide for NXP LS1043 (Rev. B)
 - TPS65086100 OTP Generator for LS1043A (Rev. B)

The User's Guide shows that the TPS650861 PMIC manage the PORESET signal of the LS1043A by its GPO1 output.
However, I do not see any command that would produce this function in the "OTP Generator for LS1043A (Rev. B)".

Did I miss anything ? Or is there a lack in the programming code ?

Thanks,
Samuel
