10/100 Mbits/s Ethernet Transceiver Macrocell
Advance Data Sheet
March 2000
Signal Information (continued)
LEDs operate as follows:
LED_STR_EN = 0, LED_BLINK_EN = 0 => No stretching/blinking.
LED_STR_EN = 1, LED_BLINK_EN = 0 => Stretch to 42 ms, minimum.
LED_STR_EN = 0, LED_BLINK_EN = 1 => Every activity causes 42 mS ON, 42 mS OFF blink.
LED_STR_EN = 1, LED_BLINK_EN = 1 => Every activity causes 0.5 second ON, 0.5 second OFF blink.

Signal
Type
Name/Description
4
XS[5:0]
O Transmit Status. This signal indicates transmit activity. This output can be
stretched or blinked per the description given above.
RS[5:0]
O Receive Status. This signal indicates receive activity. This output can be
stretched or blinked per the description given above.
CS[5:0]
O Collision Status. This signal indicates collision occurrence. This output can
be stretched or blinked per the description given above.
LS10_OK[5:0]
O Link10. This signal indicates good link status for 10 Mbits/s.
LS100_OK[5:0]
O Link100. This signal indicates good link status for 100 Mbits/s.
LS_OK[5:0]
FDUP_OUT[5:0]
O Link Status. Indicates link status.
O Full-Duplex Status. If this signal is high, it indicates full-duplex link, and if it is
low, then the link is half duplex.
TPJS[5:0]
O Jabber Status. Indicates that there is a jabber condition (only in 10 Mbits/s).
TPAPS[5:0]
O TP Autopolarity Status. Indicates if autopolarity has been detected and
corrected.
