10/100SEL
2
Input or
Output
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:
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.
10/LP
28
Input
10M Serial / Link Pulse (Stream Interface).
For this pin to have any affect on the MAC/Repeater Interface:
– The 10/100SEL pin must be logic zero (that is, 10-MHz mode).
– The MII/SI pin must be logic one (that is, Stream Interface mode).
When both the 10/100 SEL and MII/SI pins are set as required,
then this 10/LP pin selects between the 10M Serial Interface and
the Link Pulse Interface for the MAC/Repeater Interface. When the
signal on this pin is logic:
– Low, this pin selects the 10M Serial Interface.
– High, this pin selects the Link Pulse Interface.
10TCSR
3
Input
10M Transmit Current Set Resistor.
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
Section 10.3,
“Recommended Component Values”
.
100TCSR
4
Input
100M Transmit Current Set Resistor.
A resistor, connected between this pin and ground, is required to
establish the value of the transmit current used in 100Base-TX
mode.
The value and tolerance of this resistor is specified in
Section 10.3,
“Recommended Component Values”
.
ANSEL
64
Input or
Output
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:
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.
