Description
LED0_MODE 3:0 0110b
1
LED0/LINK# Mode
This field specifies the control source for the LED0 output. An initial value of 0110b
selects the LINK100# indication.
LED_PCI_MODE 4 0b
0b = Use LEDs as defined in the other fields of this register.
1b = Use LEDs to indicate PCI3 lanes idle status in SDP mode (only when the
led_mode is set to 0x8 – SDP mode)
LED0 indicates electrical idle status.
GLOBAL_BLINK_
MODE
50b
1
Global Blink Mode
This field specifies the blink mode of all the LEDs.
0b = Blink at 200 ms on and 200 ms off.
1b = Blink at 83 ms on and 83 ms off.
LED0_IVRT 6 0b
1
LED0/LINK# Invert
This field specifies the polarity / inversion of the LED source prior to output or blink
control.
0b = Do not invert LED source (LED active low).
1b = Invert LED source (LED active high).
In mode 0100b (link/activity) this field must be 0. The LED signal must be active low
in mode 0100b (link/activity).
LED0_BLINK 7 0b
1
LED0/LINK# Blink
This field specifies whether to apply blink logic to the (possibly inverted) LED control
source prior to the LED output.
0b = Do not blink asserted LED output.
1b = Blink asserted LED output.
LED1_MODE 11:8 0100b
1
LED1/LINK/ACTIVITY
This field specifies the control source for the LED1 output. An initial value of 0100b
selects the LINK/ACTIVITY indication. When asserted, means the LINK indication and
when BLINK means LINK and ACTIVITY.
Reserved 13:12 0b
Reserved
Write as 0x0,ignore on read.
LED1_IVRT 14 0b
1
LED1/ACTIVITY# Invert
This field specifies the polarity / inversion of the LED source prior to output or blink
control.
0b = Do not invert LED source (LED active low).
1b = Invert LED source (LED active high).
In mode 0100b (link/activity) this field must be 0. The LED signal must be active low
in mode 0100b (link/activity).
LED1_BLINK 15 1b
1
LED1/ACTIVITY# Blink
LED2_MODE 19:16 0111b
1
LED2/LINK1000# Mode
This field specifies the control source for the LED2 output. An initial value of 0111b
selects the LINK1000# indication.
Reserved 21:20 0x0
Reserved.
Write 0b, ignore on read.
LED2_IVRT 22 0b
1
LED2/LINK100# Invert
This field specifies the polarity / inversion of the LED source prior to output or blink
control.
0b = Do not invert LED source (LED active low).
1b = Invert LED source (LED active high).
In mode 0100b (link/activity) this field must be 0. The LED signal must be active low
in mode 0100b (link/activity).
LED2_BLINK 23 0b
1
LED2/LINK100# Blink
