Detailed Description

Function Documentation

static void AUXSMPHAcquire ( uint32_t  ui32Semaphore )

inlinestatic

Acquire an AUX semaphore.

This function acquires the given AUX semaphore, blocking the call until the semaphore is available.

Note

The semaphore can also be acquired by the dedicated Sensor Controller. The System CPU master can thus be competing for the shared resource, i.e. the specified semaphore.

Parameters

ui32Semaphore

is the semaphore number. AUX_SMPH_0 AUX_SMPH_1 AUX_SMPH_2 AUX_SMPH_3 AUX_SMPH_4 AUX_SMPH_5 AUX_SMPH_6 AUX_SMPH_7

Returns

None

static void AUXSMPHRelease ( uint32_t  ui32Semaphore )

inlinestatic

Release an AUX semaphore by System CPU master.

This function releases the given AUX semaphore.

Note

It is up to the application to provide the convention for clearing semaphore.

The semaphore can also be acquired by the dedicated Sensor Controller. The System CPU master can thus be competing for the shared resource, i.e. the specified semaphore.

Parameters

ui32Semaphore

is the semaphore number. AUX_SMPH_0 AUX_SMPH_1 AUX_SMPH_2 AUX_SMPH_3 AUX_SMPH_4 AUX_SMPH_5 AUX_SMPH_6 AUX_SMPH_7

Returns

None

static bool AUXSMPHTryAcquire ( uint32_t  ui32Semaphore )

inlinestatic

Try to acquire an AUX semaphore.

This function tries to acquire the given AUX semaphore, if the semaphore could not be claimed the function returns false.

Note

The semaphore can also be acquired by the dedicated Sensor Controller. The System CPU master can thus be competing for the shared resource, i.e. the specified semaphore.

Parameters

ui32Semaphore

is the semaphore number. AUX_SMPH_0 AUX_SMPH_1 AUX_SMPH_2 AUX_SMPH_3 AUX_SMPH_4 AUX_SMPH_5 AUX_SMPH_6 AUX_SMPH_7

Returns

Returns true if semaphore was acquired, false otherwise
