The same functionality as given for the transmit direction applies in receive direction.
4.1.3
A local port loop can be closed in the port interface. It mirrors the outgoing bit stream of
one port to the receive part of the same port. This allows to prepare data in system
memory, which is processed by the MUNICH256 in transmit direction, mirrored to the
receiver and stored in system memory again. In order to ensure that the local port loop
works even without an incoming receive clock, the receiver of the selected port is
operated with the transmit clock.
When closing the local port loop, the corresponding transmit clock TCLK(x) and transmit
frame synchronization pulse TSP(x) are used to operate the transmitter and the receiver.
Receive data RD(x), the receive clock RCLK(x) and the receive synchronization pulse
RSP(x) are ignored in that case.
