level (1) 		Slew rate control when I2C_EN/PIN = Low.
SLEW_CTL = H, fastest data rate
SLEW_CTL = L, 5 ps slow
SLEW_CTL = No Connect, 10 ps slow
When I2C_EN/PIN = High Slew rate is controlled through I2C[4]
PRE_SEL 20 16 I
3
level (1) 		De-emphasis pin strap when I2C_EN/PIN = Low.

I2C_EN/PIN 10 8 I I2C_EN/PIN = High; puts device into I2C control mode
I2C_EN/PIN = Low; puts device into pin strap mode
SCL_CTL 15 13 I I2C clock signal

When I2C_EN/PIN = High
Address bit 2
Note: Weak internal pull down
TX_TERM_CTL(2) 36 N/A I

2 Gbps < DR < 3.4 Gbps – 150- to 300-Ω differential near end termination
DR < 2 Gbps – no termination
Note: If left floating will be in automatic select mode.
SWAP/POL(2) 1 N/A I
