Set physical transmit output current.
Pull down this pin with a 3.01K 1% resistor to ground.
Analog ground
1.8V analog VDD for PLL
Analog ground
25 MHz crystal/oscillator clock connections
Note: Clock is +/- 50ppm for both crystal and oscillator.
Hardware reset pin (active low)
Half Duplex Backpressure
Special Mac Mode
LED display mode select
See description in pin# (1,4).
Switch MII transmit enable
Pins (X1, X2) connect to a crystal. If an oscillator is used, X1 connects
to a 3.3V tolerant oscillator and X2 is a no connect.
1 = enable
0 = disable
1 = enable
0 = disable
In this mode, the switch will do faster backoffs than normal.
