PATTn[1:0]: Transmit test pattern select (per channel control)
In hardware control mode, these pins select the transmit pattern for channel n (n=1 or 2)
00 = normal
01= All Ones

LPn[1:0]: Loopback mode select (per channel control)
When the chip is configured by hardware, these pins are used to select loopback operation modes for channel n (Inband loopback
is not provided in hardware control mode).
00= no loopback
01= analog loopback
10= digital loopback
11= remote loopback

THZ
THZ: Transmitter Driver High Impedance Enable (global control)
This signal enables or disables both of the transmitter drivers. A low level on this pin enables both of the two drivers while a high
level on this pin places both of the two drivers in high impedance state.

RCLKE
RCLKE: the active edge of RCLKn select when hardware control mode is used (global control)
0= select the rising edge as active edge of RCLKn
1= select the falling edge as active edge of RCLKn
