12.7.2 Diagnostic Digital Loopback  
When Diagnostic Digital loopback (DDLB) mode is initiated by setting the DDLB bit in the Line  
Interface Diagnostics Register to logic 1, the OCTLIU octant is configured to internally direct the  
output of the TJAT to the inputs of the receiver section. The dual-rail RZ outputs of the TJAT are  
directed to the dual-rail inputs of the CDRC. Conceptually, the data flow through a single octant  
of the OCTLIU in this loopback condition is illustrated in Figure 19.

12.8 JTAG Support  
The OCTLIU supports the IEEE Boundary Scan Specification as described in the IEEE 1149.1  
standards. The Test Access Port (TAP) consists of the five standard pins, TRSTB, TCK, TMS,
