SUS Power Well Power-Up Sequence From the G3 State

Refer to

, and

Some of the pin-based straps (hard straps) values are sampled by the SoC when the

active-low RSMRST_B signal is deasserted. These “SUS Power OK” hard strap values

must be valid for at least 400 ns after RSMRST_B signal is deasserted. Hard straps are

. Important to the

SoC power-up sequence is the sampling of the SoC pin Y65 which is the “After G3

Enable” (AG3E) hard strap. Its effect is mentioned later.
