Description
LED_SEL[1:0]
IPH
LED output mode selection
They are latched at the end of reset to select the LED output
mode
LED_SEL[1:0]=2’b00: LED mode 0,
LED_SEL[1:0]=2’b01: LED mode 1,
LED_SEL[1:0]=2’b10: LED mode 2,
LED_SEL[1:0]=2’b11: LED mode 3 (default)
After reset, IP113 reads EEPROM with LED_SEL[1:0], which
works as EECS and EESK. These two pins are output signals
during reading EEPROM. After finishing reading EEPROM,
these two pins becomes input signal to isolate IP113 from
EEPROM
Link, Activity (output after reset)
LED mode0: Link+Activity
(off: Link fail, on:Link ok and no activity,
flash: Link ok and TX/RX activity)
LED mode1: Receive activity
(off: not receiving, flash: receiving)
LED mode2: Tx/Rx Activity
(off: no activity, flash: TX or RX activity)
LED mode3: Link+Activity
(off: Link fail, on:Link ok and no activity,
flash: Link ok and TX/RX activity)
Full/half, Collision, Tx Activity (output after reset)
LED mode0: Collision
(off: no collision, flash: when collision happens)
LED mode1: Tx activity
(1: no TX activity, flash: when TX activity happens)
LED mode2, 3: Full+collision
(1: half without collision, 0: full, flash: collision)
Full/half, Link (output after reset)
LED mode0, Full/half: (off: half, on: full)
LED mode1, Link: (off: Link fail, on: Link ok)
LED mode2, Link: (off: Link fail, on: Link ok)
LED mode3: same as mode 0
Speed (output after reset)
LED mode0: (off: speed=10M, on: speed=100M)
LED mode1: (off: speed=10M, on: speed=100M)
LED mode2: (off: speed=10M, on: speed=100M)
LED mode3: (off: speed=10M, on: speed=100M)
