MYXPM6021*

Form #: CSI-D-685 Document 011

Events Condition to be Fullled Comments

Battery Becomes Valid BATLOW_B = 1

ADPWAKEEN = 1

Battery present. AC/DC insertion event

(DCBOOT = 0). The wakeup is only

delayed till battery is charged enough

(VBAT > BATLOW).

BATLOW_B = 1

USBWAKEEN = 1

Battery present. USB insertion event.

The wakeup is only delayed till battery is

charged enough.

Power Button BATLOW_B = 1 System running on battery

PWRBTNWAKE.USBWAKE = 01

PWRBTNWAKE.USBWAKE = 10

Battery present and charging from USB.

Battery still not charged enough.

01 = Wakeup due to DCP charging

source.

11 = Wakeup due to SDP (500mA)

source.

If the battery can only source 100mA,

then the system will not boot.

PWRBTNWAKE.ACDCWAKE = 1

DCBOOT = 0

Battery present and charging from AC/

DC. Battery still not charged enough.

DCBOOT = 1

BSTRMDETRN = 0

Wakeup immediately
