Advertisement Bits

Use bits 9:5 of the Advertisement register to customize the ability information transmitted to the link partner. The default

value for each bit reflects the abilities of the BCM5220. By writing a 1 to any of the bits, the corresponding ability can be

transmitted to the link partner. Writing a 0 to any bit causes the corresponding ability to be suppressed from transmission.

Resetting the chip restores the default bit values. Reading the register returns the values last written to the corresponding

bits, or else the default values if no write has been completed since the last chip reset.

Selector Field

Bits 4:0 of the Advertisement register contain the value 00001, indicating that the chip belongs to the 802.3 class of PHY

transceivers.
