Applies to: RTX51 Real-time Kernel

Answer

QUESTION

When does the Signal flag get cleared for the task waiting on the signal?

ANSWER

If the task is waiting for a signal, then the flag clears upon receipt of the signal. Otherwise, the flag is set and will clear upon the next execution time of the task. The flag is not a buffer and subsequent signals are lost.
