Detailed Description

Enumeration Type Documentation

mxc_lp_riscv_clock_t

enum mxc_lp_riscv_clock_t

Enumeration type for RISC-V clock selection.

Enumerator
MXC_LP_RISCV_CLOCK_ISO	Select the Internal Secondary Oscillator (ISO) as the RISCV clock source
MXC_LP_RISCV_CLOCK_PCLK	Select the Advanced Peripheral Bus (APB) clock as the RISCV clock source

Function Documentation

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 /ref MXC_Error_Codes

MXC_LP_DisableCANWakeup()

void MXC_LP_DisableCANWakeup

(

uint32_t

can_idx

)

Disables CAN from waking up the device.

Parameters

can_idx

Selects which CAN instance to disable wakeup events for

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_DisableLPCMPWakeup()

void MXC_LP_DisableLPCMPWakeup

(

mxc_lpcmp_cmpsel_t

cmp

)

Disables the comparators from waking up the device.

Parameters

cmp	Selects the comparator to disable wakeup events for

MXC_LP_DisableTimerWakeup()

void MXC_LP_DisableTimerWakeup

(

mxc_tmr_regs_t *

tmr

)

Disables Timer from waking up device.

Parameters

tmr	Pointer to timer module.

MXC_LP_EnableCANWakeup()

void MXC_LP_EnableCANWakeup

(

uint32_t

can_idx

)

Enables CAN to wake up the device from any low power mode.

Parameters

can_idx

Selects which CAN instance to enable wakeup events for

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_EnableLPCMPWakeup()

void MXC_LP_EnableLPCMPWakeup

(

mxc_lpcmp_cmpsel_t

cmp

)

Enables the comparators to wake up the device from any low power mode.

Parameters

cmp	Selects the comparator to enable wakeup events for

MXC_LP_EnableTimerWakeup()

void MXC_LP_EnableTimerWakeup

(

mxc_tmr_regs_t *

tmr

)

Enables Timer to wakeup from any low power mode.

Parameters

tmr	Pointer to timer module.

MXC_LP_RISCVClockSelect()

int MXC_LP_RISCVClockSelect

(

mxc_lp_riscv_clock_t

clock

)

Set the clock source for the RISC-V core used in Low-Power Mode.

Parameters

clock

The clock source to set

Returns

0 if successful, Error Codes on errors

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
