3.1.1
Link status output (LS) (PIN 2)
The Link Status PIN 2 outputs a weak 3.3 Volts status signal. There is an integrated
5K Ohm pull-up resistor to 3.3 Volts. This PIN is active low. The pull-down transistor
can drain up to 100mA.
3.1.2
Force link down (LD) (PIN 3)
If you connect PIN 3 and PIN 1 by a shortcut wire link down is forced. These pins are
active low. There is an integrated 5K Ohm Pullup to 3.3 Volts. For normal operation
please disconnect the PINs.
While removing the shortcut of PIN 3 and PIN 1, a full reset of the device will be
done.
Power reset is not needed
3.1.3
Force slave mode (FS) (PIN 4)
If you connect PIN 4 and PIN 1 by a shortcut wire Force Slave mode is activated.
These pins are active low. There is an integrated 5K Ohm Pullup to 3.3 Volts.
For normal operation please disconnect the PINs.
Activated Force Slave mode overrides the DIP switch configuration.
Power reset is not needed
