ICS1893 Data Sheet - Release

P2LI

Input or

Output

PHY (Address Bit) 2 / Link Integrity LED.

For more information on this pin, see Section 6.8, “Status Interface”.

• This multi-function configuration pin is:

– An input pin during either a power-on reset or a hardware reset. In

this case, this pin configures the address of the ICS1893 when it is in

either hardware mode or software mode.

– An output pin following reset. In this case, this pin provides link status

for the ICS1893.

As an input pin:

• This pins establishes the address for the ICS1893. When the signal on

this pin is logic:

– Low, that address bit is set to logic zero.

– High, that address bit is set to logic one.

As an output pin:

• When the signal on this pin is:

– De-asserted, this state indicates the ICS1893 does not have a link.

– Asserted, this state indicates the ICS1893 has a valid link.

Caution:

This pin must not float. (See the notes at Section 9.3.2,

“Multi-Function (Multiplexed) Pins: PHY Address and LED

Pins”.)

P3TD

Input or

Output

PHY (Address Bit) 3 / Transmit Data LED.

For more information on this pin, see Section 6.8, “Status Interface”.

• These multi-function configuration pins are:

– Input pins during either a power-on reset or a hardware reset. In this

case, these pins configure the address of the ICS1893 when it is in

either hardware mode or software mode.

– Output pins following reset. In this case, this pin provides link status

for the ICS1893.

As an input pin:

• This pin establishes the address for the ICS1893. When the signal on

one of these pins is logic:

– Low, that address bit is set to logic zero.

– High, that address bit is set to logic one.

As an output pin:

• When the signal on this pin is:

– De-asserted, this state indicates the ICS1893 does not have a link.

– Asserted, this state indicates the ICS1893 has a valid link.

Caution:

This pin must not float. (See the notes at Section 9.3.2,

“Multi-Function (Multiplexed) Pins: PHY Address and LED

Pins”.)
