FUNCTION
TYPE
DESCRIPTION
2:1
Cut-through
Threshold
RW
Cut-through Threshold. When forwarding a packet from low-speed port to
high-speed mode, the chip provides the capability to adjust the forwarding
threshold. The default value may be changed by SMBus or auto-loading from
EEPROM.
00b: the threshold is set at the middle of forwarding packet
01b: the threshold is set ahead 1-cycle of middle point
10b: the threshold is set ahead 2-cycle of middle point.
11b: the threshold is set ahead 3-cycle of middle point.
Reset to 01b.
3
Port Arbitration
Mode
RW
When set, the round-robin arbitration will stay in the arbitrated port even if
the credit is not enough but request is pending.
When clear, the round-robin arbitration will always go to the requesting port,
which the outgoing credit is enough for the packet queued in the port.
The default value may be changed by SMBus or auto-loading from
EEPROM.
Reset to 0b.
4
Credit Update Mode
RW
When set, the frequency of releasing new credit to the link partner will be one
credit per update.
When clear, the frequency of releasing new credit to the link partner will be
two credits per update.
The default value may be changed by SMBus or auto-loading from
EEPROM.
Reset to 0b.
5
Ordering on
Different Egress Port
Mode
RW
When set, there has ordering rule on packets for different egress port. The
default value may be changed by SMBus or auto-loading from EEPROM.
Reset to 0b.
6
Ordering on
Different Tag of
Completion Mode
RW
When set, there has ordering rule between completion packet with different
tag. The default value may be changed by SMBus or auto-loading from
EEPROM.
Reset to 0b.
7
Reserved
RO
Reset to 0.
13:8
Power management
Control parameter
RW
The default value may be changed by SMBus or auto-loading from
EEPROM.
Reset to 000001b.
14
RX Polarity
Inversion Disable
RO
The default value may be changed by SMBus or auto-loading from
EEPROM.
Reset to 0b.
15
Compliance pattern
Parity Control
Disable
RO
The default value may be changed by SMBus or auto-loading from
EEPROM.
Reset to 0b.
16
Low Driver Current
HwInt
It indicates the status of the strapping pin LODRV. The default value may be
changed by SMBus or auto-loading from EEPROM.
17
High Driver Current
HwInt
It indicates the status of the strapping pin HIDRV. The default value may be
changed by SMBus or auto-loading from EEPROM.
21:18
Driver Transmit
Current
HwInt
It indicates the status of the strapping pins DTX[3:0]. The default value may
be changed by SMBus or auto-loading from EEPROM.
25:22
De-emphasis
Transmit
Equalization
HwInt
It indicates the status of the strapping pins DEQ[3:0]. The default value may
be changed by SMBus or auto-loading from EEPROM.
27:26
Receive Termination
Adjustment
HwInt
It indicates the status of the strapping pins RXTRMADJ[1:0]. The default
value may be changed by SMBus or auto-loading from EEPROM.
29:28
Transmit
Termination
Adjustment
HwInt
It indicates the status of the strapping pins TXTRMADJ[1:0]. The default
value may be changed by SMBus or auto-loading from EEPROM.
