EQ1 14 4 Level I This pin along with EQ0 sets the USB receiver equalizer gain for upstream facing RX1 and RX2 when USB used. Up to 11dB of EQ available.
EQ0 11 4 Level I This pin along with EQ1 sets the USB receiver equalizer gain for upstream facing RX1 and RX2 when USB used. Up to 11 dB of EQ available.
EN 29 2 Level I
(PD) 		Device Enable, when I2C_EN = '0'. Device disable function not used when I2C_EN ≠ '0'.
L = Device Disabled
H = Device Enabled
On rising edge of EN pin, the device will sample all 4-level inputs including the I2C_EN pin. EN pin will not reset the I2C registers.
HPDIN 32 2 Level I Hot Plug Detect. This pin is an input for Hot Plug Detect received from DisplayPort sink. When HPDIN is Low for greater than 2ms, all DisplayPort lanes are disabled while the AUX to SBU switch will remain closed.
I2C_EN 17 4 Level I I2C Programming Mode or GPIO Programming Select. I2C is only disabled when this pin is ‘0'.
0 = GPIO mode (I2C disabled)
R = TI Test Mode (I2C enabled at 3.3 V)
F = I2C enabled at 1.8 V
1 = I2C enabled at 3.3 V.
