10Base-T / 100Base-TX Select.
The ‘Pin Type’ for this pin depends on the setting for the HW/SW pin
(pin 23). When the HW/SW pin is set for:
10M Transmit Current Set Resistor.
100M Transmit Current Set Resistor.
Auto-Negotiation Select.
The ‘Pin Type’ for this pin depends on the setting for the HW/SW pin
(pin 23). When the HW/SW pin is set for:
Half-Duplex / Full-Duplex Select.

Hardware mode, this pin acts as an input. In this case, when the
signal on this pin is logic:
– Low, this pin selects 10Base-T operations.
– High, this pin selects 100Base-TX operations.
Software mode, this pin acts as an output that indicates the current
status of this pin. In this case, when the signal on this pin is logic:
– Low, this pin indicates 10Base-T operations are selected.
– High, this pin indicates 100Base-TX operations are selected.
A resistor, connected between this pin and ground, is required to
establish the value of the transmit current used in 10Base-T mode.
The value and tolerance of this resistor is specified in
“Recommended Component
A resistor, connected between this pin and ground, is required to

Hardware mode, this pin acts as an input. In this case, when the
signal on this pin is logic:
– Low, this pin does not select Auto-Negotiation operations.
– High, this pin selects Auto-Negotiation operations.
Software mode, this pin acts as an output that indicates the current
status of this pin. In this case, when the signal on this pin is logic:
– Low, this pin indicates that Auto-Negotiation is disabled.
– High, this pin indicates that Auto-Negotiation is enabled.
Hardware mode, this pin acts as an input. In this case, when the
signal on this pin is logic:
– Low, this pin selects half-duplex operations.
– High, this pin selects full-duplex operations.
Software mode, this pin acts as an output that indicates the current
status of this pin. In this case, when the signal on this pin is logic:
– Low, this pin indicates that it is set for half-duplex operations.
– High, this pin indicates that it is set for full-duplex operations.
