described in the PIN Description section.
8.6.1 FIRST MODE - 3 LED DISPLAYS FOR
100Mbps(on) or 10Mbps(off)
Link (Keeps on when link ok) or Activity (Blink with 10Hz when receiving or
transmitting but not collision)
FD (Keeps on when in Full duplex mode) or Collision (Blink with 20Hz when colliding)
8.6.2 SECOND MODE – 4 LED DISPLAYS FOR
100 Link (On when 100M link ok)
10 Link (On when 10M link ok)
Activity (Blink with 10Hz when receiving or transmitting)

8.7 RESET OPERATION
8.7.1 RESET WHOLE CHIP
There are two ways to reset the AN983B.
First, hardware reset, the AN983B can be reset via RST#
pin. For ensuring proper reset operation, at least 100
µs active Reset input signal is required. Second,
software reset, when bit 0 of CSR0 register is set to 1, the AN983B will reset entire circuits and
register to default value then clear the bit 0 of CSR0 to 0.
8.7.2 RESET TRANSCEIVER ONLY
