AS7000 − Detailed Description

Figure 84:

CCU_LP_CFG

The CCU_LP registers controls the low power modes

Figure 85:

CCU_LP_CTRL

Note(s):

1. Only use ams SDK to enter deep sleep mode, do not set bit directly.

0x60: CCU_LP_CFG

Field

Name

Rst

Type

Description

15:0

sleep_counter

When going into low power sleep, this the sleep counter

start value in slow clock ticks. As soon as it reaches zero,

the CPU will wake up (if the register was written with a non

zero value)

gpio7_wakeup_

0RW

If asserted, setting GPIO7 to high can wake up the chip as

well (from both sleep and powerdown)

gpio8_wakeup_

0RW

If asserted, setting GPIO8 to low can wake up the chip from

deep sleep (GPIO8=low always wakes up from

powerdown)

0x64: CCU_LP_CTRL

Field

Name

Rst

Type

Description

enter_sleep

Writing a 1 here makes the system enter deep sleep mode

(wakeup by counter reaching zero) (1)

enter_

powerdown

Writing a 1 here makes the system enter power down

mode (wakeup by GPIO)
