LED0_EN

LED 0 Enable. A disabled LED is off. An enabled LED can be on or blinking depending on

LED0_FUNCTION selection and activity

0x1

R/W

LED0_LINK_ST_QUALIFY

Qualify Certain LED 0 Options with link_status.

0x0

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.

LED0_MODE

LED 0 Mode Selection.

0x0

R/W

0: LED Mode 1. If activity, blink at the rate defined by MMR LED0_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

duration and shorter on duration. The activity level is reevaluated after a window period that varies between

640 ms and 1.5 sec.

[4:0]

LED0_FUNCTION

LED_0 Pin Function. Determines the source activity for the LED_0 pin.

0x0

R/W

The CLK25_REF, TX_TCLK, CLK_120MHZ options are clock out features with the LED controller bypassed.

The waveform transmitted off chip is dependent on the selected clock source frequency.

The following LED_FUNCTION settings are not qualified with link_status: LED_FUNCTION =

on, off, blink, INCOMPATIBLE_LINK_CFG, AN_LINK_GOOD, AN_COMPLETE, LOC_RCVR_STATUS,

REM_RCVR_STATUS, CLK25_REF, TX_TCLK and CLK_120MHz.

Options TX_LEVEL_2P4, TX_LEVEL_1P0, master, and slave are optionally qualified by link status and this

is controlled via the LED0_LINK_ST_QUALIFY MMR.

The TX_LEVEL_2P4, TX_LEVEL_1P0, master, slave, MSTR_SLV_FAULT, AN_LINK_GOOD,

AN_COMPLETE, and TS_TIMER. These options are considered status indicators and the LED controller is

not used. If the programmed signal is high, the LED is static on and if the programmed signal is low, the

LED is static off.

0: LINKUP_TXRX_ACTIVITY.

1: LINKUP_TX_ACTIVITY.

2: LINKUP_RX_ACTIVITY.

3: LINKUP_ONLY.

4: TXRX_ACTIVITY.

5: TX_ACTIVITY.

6: RX_ACTIVITY.

7: LINKUP_RX_ER.

8: LINKUP_RX_TX_ER.

9: RX_ER.

10: RX_TX_ER.

11: TX_SOP.

12: RX_SOP.
