Detailed Description

Function Documentation

hal_pwr_config_ext_wakeup()

void hal_pwr_config_ext_wakeup	(	uint32_t	ext_wakeup_pinx,
		uint32_t	ext_wakeup_type
	)

Configure the External AON GPIO pins and pin trigger type that is used to wakeup MCU.

Parameters

[in]	ext_wakeup_pinx	This parameter can be a combination of the following values: PWR_EXTWKUP_PIN0 PWR_EXTWKUP_PIN1 PWR_EXTWKUP_PIN2 PWR_EXTWKUP_PIN3 PWR_EXTWKUP_PIN4 PWR_EXTWKUP_PIN5 PWR_EXTWKUP_PIN_ALL
[in]	ext_wakeup_type	This parameter can be a combination of the following values: PWR_EXTWKUP_TYPE_LOW PWR_EXTWKUP_TYPE_HIGH PWR_EXTWKUP_TYPE_RISING PWR_EXTWKUP_TYPE_FALLING

Note

When the level of any selected GPIO pin changes in accordance with the set trigger type, MCU will be waked up from DeepSleep mode.

hal_pwr_config_timer_wakeup()

void hal_pwr_config_timer_wakeup	(	uint8_t	timer_mode,
		uint32_t	load_count
	)

Configure the AON Sleep Timer mode and count used to wakeup MCU.

Parameters

[in]	timer_mode	Specifies the sleep timer mode. This parameter can be a combination of the following values: PWR_SLP_TIMER_MODE_NORMAL PWR_SLP_TIMER_MODE_SINGLE PWR_SLP_TIMER_MODE_RELOAD PWR_SLP_TIMER_MODE_DISABLE
[in]	load_count	Count value of the AON Sleep Timer.

Note

The sleep clock of AON Timer is 32 KHz.

hal_pwr_disable_ext_wakeup()

void hal_pwr_disable_ext_wakeup

(

uint32_t

disable_wakeup_pinx

)

Disable the interrupt wake-up function of the specified AON GPIO pin.

Parameters

[in]

disable_wakeup_pinx

This parameter can be a combination of the following values: PWR_EXTWKUP_PIN0 PWR_EXTWKUP_PIN1 PWR_EXTWKUP_PIN2 PWR_EXTWKUP_PIN3 PWR_EXTWKUP_PIN4 PWR_EXTWKUP_PIN5 PWR_EXTWKUP_PIN_ALL

hal_pwr_enter_chip_deepsleep()

void hal_pwr_enter_chip_deepsleep

(

void

)

Enters DeepSleep mode.

Note

In DeepSleep mode, all I/O pins keep the same state as in Run mode.

hal_pwr_set_wakeup_condition()

void hal_pwr_set_wakeup_condition

(

uint32_t

condition

)

Set the DeepSleep WakeUp Condition.

Parameters

[in]

condition

This parameter can be a combination of the following values: PWR_WKUP_COND_EXT PWR_WKUP_COND_TIMER PWR_WKUP_COND_BLE PWR_WKUP_COND_CALENDAR PWR_WKUP_COND_BOD_FEDGE PWR_WKUP_COND_MSIO_COMP PWR_WKUP_COND_ALL

Note

When PWR_WKUP_COND_EXT is set, use hal_pwr_config_ext_wakeup() to configure wakeup pins and pin trigger type. When PWR_WKUP_COND_TIMER is set, use hal_pwr_config_timer_wakeup() to configure the time count to wakeup. When PWR_WKUP_COND_ALL is set, use hal_pwr_config_ext_wakeup() and hal_pwr_config_timer_wakeup() to configure AON timer and External AON GPIO.
