FUNCTIONAL DESCRIPTION
Port Status Registers
The Port Status registers (address 001) contain portspecific information regarding the operational or faulted
state of each of the eight Ethernet ports, as shown in Tables 4 and 5. In addition, the Port 1 Status register
(Register/Port address xx00/1000) bits D6:D3 contain the current usage information of some of the common
hardware resources, as they are accessed in the servicing of the port presently selected by the master
sequencer.
