MCF52223 EVB Documentation?

[GPS]

Does anyone know where I can find documentation (schematics would be nice) of the MCF52223 evaluation board? I have the board and I am trying to twiddle the GPIO port pin shared with IRQ3. The port is configured correctly but when I look at the signal (with a voltmeter) it is always high (3.3v) no matter what I have commanded into the PORTNQ register. The other PORTNQ GPIO bits seem to change (I am using all but IRQ1 and IRQ2 as GPIO) but not the one shared with IRQ3. I'm guessing that the evaluation board has that pin connected to something that is driving it high and I can't actually use it as a GPIO on the eval board. I'm looking for documentation describing which pins on the MCU_PORT connector have restricted / decicated functions, I cannot seem to find this information.

Thanks,
Greg

I received a reply from support@axman.com, here it is:

I have attached the updated documents for Rev. B of the evaluation board to this thread for all to use.

Hi,
Could you upload the BOM please? thanks.

Thanks! And the schematics point out errors in the manual and silkscreen! Both of these show (on MCU_PORT) Pin 2 as IRQ1, Pin 31 as IRQ3 and Pin 33 as IRQ4. The schematics show Pin 2 as IRQ4, Pin 31 as IRQ1 and Pin 33 as IRQ3. The schematics are correct. I have notified support@axman.com of the errors and asked if there are any others. I will update this forum when (and if) I get a reply from them.

Thanks,
Greg

The schematics were on the CD's I got with my board.
