Function Documentation

MXC_LP_DisableGPIOWakeup()

void MXC_LP_DisableGPIOWakeup

(

const 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

(

const 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

)

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.

Note

MXC_LP_ClearWakeStatus should be called before this function, to avoid immediately waking up again

MXC_LP_EnterDeepSleepMode()

void MXC_LP_EnterDeepSleepMode

(

void

)

Places the device into DEEPSLEEP mode. This function returns once an RTC or external interrupt occur.

Note

MXC_LP_ClearWakeStatus should be called before this function, to avoid immediately waking up again

MXC_LP_EnterSleepMode()

void MXC_LP_EnterSleepMode

(

void

)

Places the device into SLEEP mode. This function returns once any interrupt occurs.

Note

MXC_LP_ClearWakeStatus should be called before this function, to avoid immediately waking up again

MXC_LP_SetOperatingVoltage()

int MXC_LP_SetOperatingVoltage

(

mxc_lp_ovr_t

ovr

)

Set operating voltage and change the clock to match the new voltage.

Parameters

system

reset configuration struct
