12:10

AN_CAPABILITY[2:0]

Value to be set in D12:D10 bits of the base link codeword. Consists of abilities

(RX)

like PAUSE, ASM_DIR (Default 3’b100)

9:5

AN_ECHO_NONCE[4:0]

Value to be set in D9:D5 bits of the base link codeword. Consists of Echo nonce

(RX)

value. Transmitted in base page only until local device and link Partner have
