Hello all,
I need more details on the \RSTOUT pin of the LPC2388.
>From the user manual:
"RSTOUT This is a 3.3 V pin. LOW on this pin indicates LPC23xx being
in Reset state."
Is this pin an open-drain or push-pull output?
I have seen a 10k pull-up resistor in some reference design... (i.e.
LPC-2478STK and others)
How does this pin work at power-up/down?
My idea was to connect this \RSTOUT pin to the \RESET input pin of the
DP83848I in order to turn-off the transceiver if a reset event occurs
(also a software reset).
Is this correct?
Shouldn't I need a pull-down resistor on the \RSTOUT pin??
In other eval. board like Keil MCB2300 the \RESET input pin of
DP83848I is directly connected to the \RESET input pin of the LPC23xx.
Regards,
Carlo

You can test for yourself whether it is open drain. When the
processor is not in reset, use a 1k pull-down resistor on the pin. It
the output goes toward and nearly to 0V then it is open drain. If the
pin voltage stays high, it is an active output.
In the User Manual, NXP says this is a 3.3V pin. In the datasheet,
they say it is a 1.8V pin. Hm... I guess you'll have to measure it.
Both schematics in both manuals show a pull-up resistor. Even if
RSTOUT* is an active output, it is sometimes useful to be certain it
pulls all the way to the rail before sending it to another chip.
But if it works for Keil without a resistor, why not try it?

FYI
Revision 01.03 (30 January 2008) of the *preliminary* data sheet now
refers to RSTOUT as a 3.3V pin (corrected the 1.8V reference).
RSTOUT This is a 3.3 V pin. LOW on this pin indicates LPC2478 being
in Reset state.

Does anybody know if the RSTOUT becomes active
when the watchdog (or brown out) hits ?

Now I am wanting to know the answer to this one... The manual
does not appear to say if the watchdog timer brings this line
low to reset the Phy peripheral.
We just had a situation where this might need to be done in order for
the ethernet to come back up after a WD timeout.

Maybe what I can do instead is to just supply a reset to the ethernet reset line using a GPIO line.... IF I have an extra one available.
