AM2432: Power-up sequencing

Part Number: AM2432

Tool/software:

Dear Team,

My customer is considering to use the AM2432 with the PMIC TPS6521907. When they checked the power-up sequencing of the AM2432 datasheet, they could not see the numbers in red on the diagram in the datasheet.
What is the requirement specification in red parts? (Even when powered down)

With the use of the TPS6521907 (PMIC), each time is expected to be 1.5ms and 6ms respectively.
(VDDS_DDR and VDDS_DDR_C of the TPS6521907 are fixed at 0V.)
Thank you.

Best Regards,

Koshi Ninomiya
