EXPANSION REGISTER 11H: CABLE DIAGNOSTIC RESULTS
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] = F11h, and read/write access is through register 15h.
Packet Counter
Bits [15:12] reflect the cable diagnostic error status of the four channels.
