Register Description
The SCAN12100 implements the device ID of 61 (0x3D.)
Other registers defined by 802.3ae-2002 are not implement-
ed in SCAN12100. The SCAN12100 has a rich MDIO register
set to allow the chip to be controlled and monitored through
software. Certain functions such as BIST and delay calibra-
tion are only accessible through MDIO.

The type of registers used in SCAN12100 are RW, RC, RO,
and WC. RW is a read and write register. RC is a read and
clear register. Upon reading the value of the RC register
through MDIO, the register will reset its value. WC is a write
and clear register. Write and clear registers are used for reset
operations. A re-read of the WC register is necessary to verify
the register has been cleared.
