PORT STATUS REGISTERS
TPS2383B
SLUS565G – JULY 2003 – REVISED AUGUST 2005
The Port Status registers (address 001) contain port specific 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.
