PHYAD_RV
AcceptErr:
EnLoop:
PHYAD_RV: When 0, port
[A]~[H]
uses PHYAD = 01000b ~ 01111b to access external PHY status.
When 1, port
[H]~[A]
uses PHYAD = 01000b ~ 01111b.
HashMode:
When 1, address hashing algorithm used for search and learning.
When 0, address direct mapping algorithm used.
If no 24LC02 is used, the default values of byte 0 and byte 1 are 00, and the default SID is 0180c2000001.
When 0, CRC error packet will be discarded for normal use.
When 1, CRC Error packet can be accepted and forwarded for test.
When 0, the Loop detection function is disabled.
When 1, the Loop detection function is enabled.
