Function Documentation

void DefaultISR ( void  )
void OSA_ProcessTasks ( void  )

This function is used to process registered tasks.

Example below shows how to use this API in baremetal.

* while(1) {
* }
*
uint8_t OSA_TaskShouldYield ( void  )

This function is used to check task should yield, When this function returns 1, an OSA task has to run. This function is typically used with Interrupt disabled before executing WFI instruction.
