Power on Enable signal generate
DOCK_PWR19
when adapter insert and U64 detect AC power OK , then generate EXTPWR.

Presentation Title
VINT19
EXTPWR_PMH generate process and Power Sequence
EXTPWR 信號 be sent to Q50 產生EXTPWR_PMH .
Of course , system need Power VL5 來打開Q50 .
VL5 generate process as next page:

Control Signal EXTPWR_PMH be sent to U72 ,
然后產生Control Signal M1_ON/M2_ON/AUX_ON
M1_ON & M2_ON&AUX_ON Sequence

Presentation Title
PWH Control Signal Sequence
這里順便了解一下PWH Control Signal Sequence
(1)
System detect EXTPWR OK then generate M_ON & AUX_ON
(2)
System detect PWRSTWITCH OK then generate A_ON &B_ON ,
也就是說﹕
System generate M_ON & AUX_ON before pressing power button
System generate A_ON & B_ON after pressing power button
