13.3.1 Port Specific Registers
13.3.2
Certain registers in the DS90UB954-Q1 are port specific and have two copies, one for each FPD-Link RX port.
The "Select RX Port" drop-down menu controls which port's registers are read. If the "Write All RX Ports" box
is checked, both ports' registers will be written to. If it is not checked, only the port indicated by the drop-down
menu will be written to. These controls set the value of register 0x4C, which is used to set which port is being
read and which port(s) are being written to.

click on the "Save" button, select the file location, and name the file. If desired, comments may be recorded
