Detailed Description

Function Documentation

__attribute__()

void __attribute__

(

(deprecated("Causes SIMO soft start in wakeup"))

)

Enable Fast Wakeup.

Deprecated due to issues with SIMO in wakeup.

MXC_LP_BandgapIsOn()

int MXC_LP_BandgapIsOn

(

void

)

Is the bandgap on or off.

Returns

1 = bandgap on , 0 = bandgap off

MXC_LP_ConfigDeepSleepClocks()

int MXC_LP_ConfigDeepSleepClocks

(

uint32_t

mask

)

Configure which clocks are powered down at deep sleep and which are not affected.

Note

Need to configure all clocks at once any clock not passed in the mask will be unaffected by Deepsleep. This will always overwrite the previous settings of ALL clocks.

Parameters

[in]

mask

The mask of the clocks to power down when part goes into deepsleep

Returns

E_NO_ERROR or error based on Error Codes

MXC_LP_DisableGPIOWakeup()

void MXC_LP_DisableGPIOWakeup

(

mxc_gpio_cfg_t *

wu_pins

)

Disables the selected GPIO port and its selected pins as a wake up source.
Call this function multiple times to disable pins on multiple ports.

Parameters

wu_pins

The port and pins to disable as wakeup sources. Only the gpio and mask fields of the structure are used. The func and pad fields are ignored.

MXC_LP_EnableGPIOWakeup()

void MXC_LP_EnableGPIOWakeup

(

mxc_gpio_cfg_t *

wu_pins

)

Enables the selected GPIO port and its selected pins to wake up the device from any low power mode.
Call this function multiple times to enable pins on multiple ports. This function does not configure the GPIO pins nor does it setup their interrupt functionality.

Parameters

wu_pins

The port and pins to configure as wakeup sources. Only the gpio and mask fields of the structure are used. The func and pad fields are ignored.

MXC_LP_EnterBackupMode()

void MXC_LP_EnterBackupMode

(

void *

funcvoid

)

Places the device into BACKUP mode. CPU state is not maintained in this mode, so this function never returns.
Instead, the device will restart once an RTC or external interrupt occur.

Parameters

func	Function that backup mode returns to, if null, the part will return to Reset_Handler

Note

When returning from backup mode, depending on the RAM retention settings the processor could have no state information. It will not have a valid stack pointer. This function also uses MXC_PWRSEQ->gp0 and gp1.

MXC_LP_FastWakeupIsEnabled()

int MXC_LP_FastWakeupIsEnabled

(

void

)

Is Fast wake up is Enabled.

Returns

1 = enabled , 0 = disabled

MXC_LP_SetOVR()

void MXC_LP_SetOVR

(

mxc_lp_ovr_t

ovr

)

Set ovr bits to set the voltage the micro will run at.

Parameters

[in]

ovr

The ovr options are only 0.9V, 1.0V, and 1.1V use enum mxc_lp_ovr_t
