9.2.2
Multi-Function (Multiplexed) Pins: PHY Address and LED Pins
Table 9-4
lists the pins for the multifunction group of pins (that is, the multiplexed PHY Address / LED pins).
Note:
1.
During either a power-on reset or a hardware reset, each multi-function configuration pin is an input
that is sampled when the ICS1892 exists the reset state. After sampling is complete, these pins are
output pins that can drive status LEDs.
A software reset does not affect the state of a multi-function configuration pin. During a software reset,
all multi-function configuration pins are outputs.
Each multi-function configuration pin must be pulled either up or down with a resistor to establish the
address of the ICS1892. LEDs placed in series with these resistors provide a designated status
indicator.
2.
3.
Caution:
All pins listed inTable 9.4 must not float.
4.
As outputs, the asserted state of a multi-function configuration pin is the inverse of the sense sampled
during reset. This inversion provides a signal that can illuminate an LED during an asserted state. For
example, if a multi-function configuration pin is pulled down to ground through an LED and a
current-limiting resistor, then the sampled sense of the input is low. To illuminate an LED for the
asserted state requires the output to be high.
Caution:
PHY Address 00 will tri-state the MII interface.
Note:
Each of these pins monitor the data link by providing signals that directly drive LEDs.

PHY (Address Bit) 3 / Transmit Data LED.
PHY (Address Bit) 4 / Receive Data LED.
The ‘Pin Type’ for these multiplexed pins depends on the where the
ICS1892 is in its reset cycle.
During a reset of the ICS1892, these pins act as inputs.
After a reset of the ICS1892, these pins latch the state of the inputs into
their respective PHY Address bits. (See
Table 8-16
.) The ICS1892 then
converts the pin signal to an output that can drive the respective LED
directly.
