Equalizer Control [4:0]:
These bits are used to control the transmit pulse shaping, transmit
line build-out (LBO) and receive sensitivity level.
The Transmit Pulse Shape can be controlled by adjusting the Trans-
mit Line Build-Out Settings for different cable length in T1 mode.
Transmit pulse shape can also be controlled by using the Arbitrary
mode, where users can specify the amplitude of the pulse shape by
using the 8 Arbitrary Pulse Segments provided in the LIU registers
(0x0F08-0x0F0F), where n is the channel number.
The XRT86VL30 device supports both long haul and short haul
applications which can also be selected using the EQC[4:0] bits.
Table 127.presents the corresponding Transmit Line Build Out and
Receive Sensitivity settings using different combinations of these
five EQC[4:0] bits.
