|
//! \section sec_mcusemaphore Introduction
|
|
//!
|
|
//! 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.
|
|
//!
|
|
//! \section sec_mcusemaphore_api API
|
|
//!
|
|
//! The API functions can be grouped like this:
|
|
//!
|
|
//! Semaphore acquire:
|
|
//! - \ref SMPHAcquire()
|
|
//! - \ref SMPHTryAcquire()
|
|
//!
|
|
//! Semaphore release:
|
|
//! - \ref SMPHRelease()
|
|
