If LEDx_FUNCTION is programmed to a combination of a link and activity signal, the LED is on while the link is up and with no activity. The

LED switches off for either loss of link or receipt of activity.

If LEDx_FUNCTION is programmed to an activity signal, the LED is off with no activity. The LED switches on upon receipt of activity.

LED0_ON_N4MS

LED_0 On Blink Time. LED_0 on blink time is calculated by 4 ms × LED0_ON_N4MS bit field.

Recommended value is greater than 3.

LED0_OFF_N4MS

LED_0 Off Blink Time. LED_0 off blink time is calculated by 4 ms × LED0_OFF_N4MS bit field.

LED_1 ON/OFF BLINK TIME REGISTER

Device Address: 0x1E; Register Address: 0x8C81, Reset: 0x3636, Name: LED1_BLINK_TIME_CNTRL

LED on blink time = LED1_ON_N4MS × 4ms.

LED off blink time = LED1_OFF_N4MS × 4 ms.

If LEDx_MODE = 0 and LEDx_FUNCTION is set to blink, the LED activity starts with an LED off sequence followed by an LED on sequence,

and then repeats.

If LEDx_MODE = 1 and LEDx_FUNCTION is set to blink, the LED activity starts with an LED on sequence, followed by an LED Off sequence,

and then repeats.

If LEDx_OFF_N4MS = LEDx_ON_N4MS = 0, this is a special case whereby the internal activity signal as selected by LEDx_FUNCTION can be

monitored live.

If LEDx_FUNCTION is programmed to a combination of a link and activity signal, the LED is on while the link is up and with no activity. The

LED switches off for either loss of link or receipt of activity.

If LEDx_FUNCTION is programmed to an activity signal, the LED is off with no activity. The LED switches on upon receipt of activity.

LED1_EN

LED 1 Enable. A disabled LED is off. An enabled LED can be on or blinking depending on LED1_FUNCTION

selection and activity.

LED1_LINK_ST_QUALIFY

Qualify Certain LED 1 Options with link_status.

R/W

0: TX_LEVEL_2P4, TX_LEVEL_1P0, master, slave not qualified by link_status.

1: TX_LEVEL_2P4, TX_LEVEL_1P0, master, slave are qualified by link_status.

LED1_MODE

LED 1 Mode Selection.

0x0

R/W

0: LED Mode 1. If there is activity, blink at the rate defined by MMR LED1_BLINK_TIME_CNTRL.

1: LED Mode 2. The LED blink frequency is set depending on the level of activity. The activity level is graded

in steps of 10%, and the frequency of the LED adjusts accordingly. A higher activity level means a longer off
