F71869A

SUS_WARN#

INst,5v

This pin asserts low when the PCH is planning to enter the

DSW power state. It can detect 5VDUAL level with delay

setting supported.

TIMING_1

OD12,5v

I_VSB3V

Active high. Timing sequence 1 of power on/off sequence

pins. The external pull high resistor is required.

(Output detected by VCCOK(VDDOK) level good, ref

Figure 15 )
