RECEIVE TUG-3 MAPPER/VC-4 POH PROCESSOR BLOCK REGISTERS (SDH/TUG-3
APPLICATIONS ONLY)
The register map for the Receive TU-3 Mapper/VC-4 POH Processor block is presented and discussed in
detail within the "SDH Version of the Register Map".
In order to provide some orientation for the reader, an illustration of the Functional Block Diagram for the
XRT86SH328 device, with the Receive TUG-3 Maper/VC-4 POH Processor block "highlighted" is presented
below in
Figure 5
.
