Detailed Description

Function Documentation

void AUXWUCClockDisable ( uint32_t ui32Clocks )

Disable clocks for peripherals in the AUX domain.

Use this function to enable specific clocks in the AUX domain.

Parameters

ui32Clocks

a bitmap of clocks to disable. Use a bitwise OR combination of the following values:

Returns: None

void AUXWUCClockEnable ( uint32_t ui32Clocks )

Enable clocks for peripherals in the AUX domain.

Use this function to enable specific clocks in the AUX domain.

Parameters

ui32Clocks

is a bitmap of clocks to enable. Use a bitwise OR combination of the following values:

Returns: None

static void AUXWUCClockFreqReq ( uint32_t ui32ClockFreq )

inlinestatic

Request a high or low frequency clock source.

Using this function it is possible to make a request to the System Control to use a high or low frequency clock as clock source for the AUX domain.

Note: A low frequency clock is always 32 kHz, while a high frequency clock is really a large span of frequencies determined by the clock source (High Frequency or Medium Frequency) and the setting for the clock divider for the AUX domain in the System Control.

Parameters

ui32ClockFreq

determines the clock source frequency.

AUX_WUC_CLOCK_LOFREQ : Request low frequency clock source for AUX domain.
AUX_WUC_CLOCK_HIFREQ : Request high frequency clock source for AUX domain.

Returns

Definition at line 232 of file aux_wuc.h.

uint32_t AUXWUCClockStatus ( uint32_t ui32Clocks )

Get the status of a clock.

Use this function to poll the status of a specific clock in the AUX domain.

Parameters

ui32Clocks

is the clock for which to return status.

Returns

Returns the status of the clock as one of two states:

static void AUXWUCFreezeDisable ( void )

inlinestatic

Unfreeze the AUX IOs.

When restarting the AUX domain after it has entered powerdown mode, the software can regain control of the IOs by setting the IO latches as transparent.

Note: The IOs should not be unfrozen before software has restored the functionality of the IO.

Returns: None

Definition at line 304 of file aux_wuc.h.

static void AUXWUCFreezeEnable ( void )

inlinestatic

Freeze the AUX IOs.

To retain the values of the output IOs during a powerdown of the AUX domain all IO latches in the AUX domain should be frozen in their current state. This ensures that software can regain control of the IOs after a powerdown without the IOs first falling back to the default values (i.e. input and pull-up).
