Write “1” to REG31H[3] to

start the sleep，and PMU will save REG10H、

REG12H、REG13H setting at that time

9.1.4.

Sleep and Wakeup

When the running system needs to enter Sleep mode, REG31H [3] will determine whether one or several power rails should

be disabled , Wakeup can be triggled by either signal：

■

ACIN plug （REG40[6:5] should be 1）

■

VBUS plug（REG40[3:2] should be 1）

■

Push long time PEK （REG42[0] should be1）

■

PEK falling edge（REG44[5] should be 1）

■

Battery low power alarm（REG43[1:0] should be 1）

■

GPIO[1:0] as a general purpose input when it detects rising and falling edge （REG4C[1:0] should be 1，and

REG90[7:6]、REF92[7:6] should be 1）

■

Software wakeup，write 1 in REG31[5]

■

IRQ wakeup ( REG8F[7] should be 1)

with all power rails resume to default voltage in default，and power on timing sequence

See control process under sleep and wakeup modes as below:：
