Important Points:
• The SWP provides flow control-based reliable communication between the
sending and receiving software tasks.
• A sending task enqueues messages into the SWP queue3 for a receiving task
and waits for an acknowledgement.
• If no response is received within a defined period of time, the SWP timeout
mechanism resubmits the message at the head of the FIFO queue.
