Detailed Description

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.

Function Documentation

void hal_atomic_end ( atomic_t * p_atomic )

Exits atomic section.

Restores status register

Parameters
[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.

Parameters
[in] p_atomic pointer to buffer to store current value of the status register.
