Module to declare HAL Atomic API.
The Atomic module implements atomic section interface. This is made by disabling the global interrupts, which is a hardware dependent feature. The user may call hal_atomic_start() to open an atomic section (disable interrupts) and hal_atomic_end() to exit from the section (restore interrupts). The algorithm supports nesting sections.
| void hal_atomic_end | ( | atomic_t * | p_atomic | ) |
Exits atomic section.
Restores status register
| [in] | p_atomic | pointer to buffer to restore current value of the status register from. |
| void hal_atomic_start | ( | atomic_t * | p_atomic | ) |
Enters atomic section.
Disables global interrupts.
| [in] | p_atomic | pointer to buffer to store current value of the status register. |
