LED 0 On/Off Blink Time Register

Device Address: 0x1E; Register Address: 0x8C80, Reset: 0x3636, Name: LED0_BLINK_TIME_CNTRL

LED on blink time = LED0_ON_N4MS × 4 ms.

LED off blink time = LED0_OFF_N4MS × 4 ms.

If LED0_MODE = 0 and LED0_FUNCTION is set to blink, the LED activity starts with an LED off sequence, followed by an LED on sequence,

and then repeats.

If LED0_MODE = 1 and LED0_FUNCTION is set to blink, the LED activity starts with an LED on sequence, followed by an LED off sequence,

and then repeats.

If LED0_OFF_N4MS = LED0_ON_N4MS = 0, this is a special case whereby the internal activity signal as selected by LED0_FUNCTION can

be monitored live.

If LED0_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 LED0_FUNCTION is programmed to an activity signal, the LED is off with no activity. The LED switches on upon receipt of activity.
