| void | SMPHAcquire (uint32_t ui32Semaphore) |
| Acquire a semaphore. More... | |
| static bool | SMPHTryAcquire (uint32_t ui32Semaphore) |
| Try to Acquire a semaphore. More... | |
| static void | SMPHRelease (uint32_t ui32Semaphore) |
| Release a semaphore. More... | |
The MCU Semaphore offers 32 semaphores that each can be claimed and released in an atomic operation. One and only one semaphore can be handled during a transaction.
Claiming a semaphore causes subsequent claims/reads to return '0' (i.e. "not available"). How the semaphores are used and respected is decided by software.
The API functions can be grouped like this:
Semaphore acquire:
Semaphore release:
| void SMPHAcquire | ( | uint32_t | ui32Semaphore | ) |

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