EXPANSION REGISTER 00H: RECEIVE/TRANSMIT PACKET COUNTER
The following expansion registers are enabled by writing to “Expansion Register Access Register (PHY_ADDR = 0x1,
Reg_Addr = 17h)” on page 434 bits [11:0] = F00h, and read/write access is through register 15h.
Packet Counter (Copper Only)
When the Packet Counter Mode bit field = 1, in the “Auxiliary Control Register (PHY_Addr = 0x1, Reg_Addr = 18h, Shadow
= 111, Misc Control)” on page 449, the number of receive packets is counted.
When the Packet Counter Mode bit field = 0, in the “Auxiliary Control Register (PHY_Addr = 0x1, Reg_Addr = 18h, Shadow
= 111, Misc Control)” on page 449, the number of transmit packets is counted. This counter is clear on read and freezes at
FFFFh.
EXPANSION REGISTER 01H: EXPANSION INTERRUPT STATUS
The following expansion registers are enabled by writing to “Expansion Register Access Register (PHY_ADDR = 0x1,
Reg_Addr = 17h)” on page 434 bits [11:0] = F01h, and read/write access is through register 15h.
Mode Select Change
This bit indicates that mode select change is detected.
SerDes Link Status Change
This bit indicates a SerDes link status change is detected.
