HT Link Width
The optional settings are :Auto
,
8 Bit
,
and 16 Bit.
HT Link Frequency
The optional settings are: Auto
,
200MHz, 4000MHz, 600 MHz , 800Mhz and 1.0 GHz.
IH Flow-Control Mode:
Isochronous (ISOC) Flow Control Mode enable will make the HT Link communication have
the complex ordering rules for Isochronous source to make sure it can get service from the
system with deterministic worst-case latency. However, the latency time cost of ISOC flow
control mode is an important consideration. Normal flow control mode will be a simpler
solution for most system.
HT Link Tristate:
Disabled mode will make the link transmitter is driven but in and under fined state during the
disconnect sequence. And the PHY (transmitter) is placed in LS0. LS0 state keeps all lanes
active to maintain DLL and phase recovery lock.
Enabled mode will make the link transmitter is placed into high impedance states during the
disconnect sequence. And the PHY (transmitter) is placed in LS1, LS2 or LS3. LS1, LS2 and
LS3 are each states that shut down parts of the PHY to save power.
LS1 state: CLK running, CAD/CTL sending TxIdle.
LS2 state: CLK/CAD/CTL sending TxIdle.
LS3 state: CLK/CAD/CTL sending either HiZ or TxGndTrm.
IH Flow-Control Mode:
Isochronous (ISOC) Flow Control Mode enable will make the HT Link communication have
the complex ordering rules for Isochronous source to make sure it can get service from the

UnitID Clumping:
The optional settings are: Auto, Disabled, PCIE, GFX and PCIE& GFX.
