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.

• After retrying a defined number of times, the SWP-2-NOMORETIMEOUT timeout

message is generated.
