12.3.1 Port Specific Registers
Certain registers in the DS90UB95x-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.
