Receive transaction layer packet FIFO empty flag. This signal
reports that the transaction layer packet FIFO is empty.
Receive transaction layer packet pending in normal queue. This
signal reports that a transaction layer packet has been
extracted from the transaction layer packet FIFO, but is still
pending for transmission to the application layer.
