Function Documentation

static void POWER_EnablePD ( pd_bit_t  en )

inlinestatic

Note that enabling the bit powers down the peripheral

Parameters

en	peripheral for which to enable the PDRUNCFG bit

Returns

none

static void POWER_DisablePD ( pd_bit_t  en )

inlinestatic

Note that disabling the bit powers up the peripheral

Parameters

en	peripheral for which to disable the PDRUNCFG bit

Returns

none

static void POWER_EnableDeepSleep ( void  )

inlinestatic

Returns

none

static void POWER_DisableDeepSleep ( void  )

inlinestatic

Returns

none

void POWER_OtpReload

(

void

)

   This API must be called if VD6 is power down
   and power back again since FROHF TRIM value
   is store in OTP. If not, when calling FROHF settng
   API in clock driver then the FROHF clock out put
   will be inaccurate.

Returns

none

void POWER_SetPLL

(

void

)

Returns

none

void POWER_SetUsbPhy

(

void

)

Returns

none

void POWER_EnterPowerMode	(	power_mode_cfg_t	mode,
		uint64_t	exclude_from_pd
	)

Parameters

mode	power mode
exclude_from_pd	Bit mask of the PDRUNCFG0(low 32bits) and PDRUNCFG1(high 32bits) that needs to be powered on during power mode selected.

Returns

none

void POWER_EnterSleep

(

void

)

Returns

none

void POWER_EnterDeepSleep

(

uint64_t

exclude_from_pd

)

Parameters

exclude_from_pd

Bit mask of the PDRUNCFG0(low 32bits) and PDRUNCFG1(high 32bits) bits that needs to be powered on during deep sleep

Returns

none

void POWER_EnterDeepPowerDown

(

uint64_t

exclude_from_pd

)

Parameters

exclude_from_pd

Bit mask of the PDRUNCFG0(low 32bits) and PDRUNCFG1(high 32bits) that needs to be powered on during deep power down mode, but this is has no effect as the voltages are cut off.

Returns

none

void POWER_SetVoltageForFreq

(

uint32_t

freq

)

Parameters

freq	- The desired frequency at which the part would like to operate, note that the voltage and flash wait states should be set before changing frequency

Returns

none

uint32_t POWER_GetLibVersion

(

void

)

Returns

version number of the power library
