Hi,
i tried to configure IO-Pin 48 as an IRQ/Input with falling edge, but it failed.
I have disabled the SDCard-driver, cause this IO is used as a card detection input.
With IO-Pin 20 & 21, which have also the capability to work as IRQ's, the reg-settings
work.
If i had a look at the debug output from DCUTerm, i can see that IO-Pin 20&21 are
configured as irq's type 2, but nothing is to see from IO-Pin48.
Any idea what's wrong?
Below are my reg settings and the debug output.
Cheers,
Tom
