5.1.1
Two basic types of test loops are provided by the MUNICH32, internal and external.
Each of these types is further subdivided into channelwise and complete test loops thus
providing four possible test loops.
5.1.1.1 Internal Complete Test Loop
The serial data output is physically routed to the serial data input. The TX data appears
on the TDATA output pin and the RDATA input pin is ignored. TCLK and RCLK have to
be identical; TSP and RSP have to be identical. The logical Transmit and Receive
channels have to be programmed identically.
