Input or
Output
PHY (Address Bit) 4 / Receive Data LED.
For more information on this pin, see Section 6.8, “Status Interface”.
The ‘Pin Type’for this multiplexed pin depends on the where the ICS1893
is in its reset cycle.
During a reset of the ICS1893, this pins acts as an input.
After a reset of the ICS1893, this pins latches the state of the inputs
into their respective PHY Address bits. (See Table 8-16.) The ICS1893
then converts the pin signal to an output that can drive the respective
LED directly.
Caution:
This pin must not float. (See the notes at Section 9.3.2,
“Multi-Function (Multiplexed) Pins: PHY Address and LED
Pins”.)
