Can taskENTER_CRITICAL_FROM_ISR() be used outside ISR?

Posted by lantczak on December 27, 2016

Hi,

Can I use taskENTERCRITICALFROM_ISR() in function that is NOT called from ISR? Will critical section work properly (preemption protection) in this case?

Best Regards Lukasz

For that port the answer is 'yes' you can use the macros outside an ISR. Note the macro returns the current interrupt status, and the value returned must then be passed into a matching call to taskEXITCRITICALFROM_ISR().
