PORTMAP (Port Mapping Control Register)
The PORTMAP register controls the SI-Bus cross-connect mappings. These controls connect the respective
SONET line side ports to the desired SI-Bus ports. Note that only one SONET port should be connected to each
SI-Bus port for reliable operation. As this is a logical switch function, temporary connection of more than one
SONET port to an SI-Bus port will not harm the part.
