clear()

uint8_t GlobalInterruptFlag::clear ( void  )

static

Clears the global interrupt flag and returns the previous value of the SREG register.

Returns

Value of SREG before clearing the global interrupt flag.

isSet()

bool GlobalInterruptFlag::isSet ( void  )

static

Returns true if global interrupt flag is set.

Returns

True if global interrupt flag is set, false otherwise.

restore()

void GlobalInterruptFlag::restore ( uint8_t  sreg )

static

Restore old state of global interrupt flag using previously stored SREG value.

Parameters

sreg	SREG value to restore global interrupt flag from

set()

void GlobalInterruptFlag::set ( void  )
