void system_enter_critical_section

(

void

)

Enters a critical section.

Disables global interrupts. To support nested critical sections, an internal count of the critical section nesting will be kept, so that global interrupts are only re-enabled upon leaving the outermost nested critical section.

References system_interrupt_enter_critical_section().

void system_leave_critical_section

(

void

)

Leaves a critical section.

Enables global interrupts. To support nested critical sections, an internal count of the critical section nesting will be kept, so that global interrupts are only re-enabled upon leaving the outermost nested critical section.
