60 Register Description (Continued)
616 PORT ATTRIBUTE STATUS REGISTER 1
The Port Attribute Status Registers 1 and 2 are located in the Port Attribute memory map of each port Port Attribute Registers 1
and 2 are used to indicate if any attributes have changed since the last CPU access to a particular port These registers
therefore provide a status indication of any attribute changes
The CPU needs to ensure that the port Attributes are cleared after a CPU read to these two registers This will guarantee that
the CPU has taken a snap-shot of the Port Attributes correctly The Management block of the DP83957 automatically updates
the attributes on a port-per-packet basis
