D01 R/W SCAN 0 Automatically scan for read data
Set to 1 to have the MII Management module perform
read cycles continuously. This is useful for
monitoring link fail, for example.
Note: SCAN must transition from a 0 to a 1 to
initiate the continuous read cycles.
D00 R/W READ 0 Single scan for read data
Set to 1 to have the MII Management module perform
a single read cycle. The read data is returned in the
MII Management Read Data register after the BUSY
bit in the MII Management Indicators register has
returned to a value of 0.
Note: READ must transition from a 0 to a 1 to
initiate a single read cycle.
