P1.24 of LPC2214 doesn't work

Started by Herbert Demmel October 11, 2006

I'm trying to use P1.24 of a LPC2214 as an output but the port pins
constantly remains at about 2.3V.

I'm using

IO1DIR |= (1 << 25);
IO1CLR = (1 << 25);

to pull the pin low (PINSEL2 bit 3 has the correct state, P1.20 is not
pulled low at reset). If I try to do the same with e.g. P1.16, everything
works as expected.

Any idea?
