Description
Flow Control Refresh Threshold (FCRT)
This value indicates the threshold value of the flow control shadow
counter. When the counter reaches this value, and the conditions for a
X
pause state are still valid (buffer fullness above low threshold value), a
pause (XOFF) frame is sent to the link partner.
The FCRTV timer count interval is the same as other flow control timers
and counts at slot times of 64-byte times.
If this field contains a zero value, the Flow Control Refresh is disabled.

Reads as 0x0.
Should be written to 0x0 for future compatibility.

Description
LED0 (LINK_UP_N) Mode
This field specifies the control source for the LED0 output. An initial
value of 0010b selects LINK_UP indication.
Reserved
Read-only as 0b. Write as 0b for future compatibility.
Global Blink Mode
This field specifies the blink mode of all LEDs.
0b = Blink at 200 ms on and 200 ms off.
1b = Blink at 83 ms on and 83 ms off.
LED0 (LINK_UP_N) Invert
This field specifies the polarity/ inversion of the LED source prior to
output or blink control.
0b = Do not invert LED source.
1b = Invert LED source.
LED0 (LINK_UP_N) Blink
This field specifies whether to apply blink logic to the (inverted) LED
control source prior to the LED output.
0b = do not blink asserted LED output.
1b = blink asserted LED output.
LED1 (ACTIVITY_N) Mode
This field specifies the control source for the LED1 output. An initial
value of 0011b selects ACTIVITY indication.
Reserved
Read-only as 0b. Write as 0 for future compatibility.
LED1 (ACTIVITY_N) Blink Mode
This field needs to be configured with the same value as
GLOBAL_BLINK_MODE, it specifies the blink mode of the LED.
0b = Blink at 200 ms on and 200 ms off.
1b = Blink at 83 ms on and 83 ms off.
LED1 (ACTIVITY_N) Invert.
