Hi,

I have a problem with pins P0.16, P0.22 which I use as chip selects for SSP0. It's very weird because they don't function as GPIO at all, at least not as outputs.

The last thing that I done was:

LPC_GPIO0->FIODIR2 = 0x41;
lcd_puts(hexByteToStr(LPC_GPIO0->FIODIR2));

The LCD printing is 0x00 !

So I can't set the pins as outputs!

The corresponding MASK is 0, the functions are 00 (GPIO), everything seems to be OK :confused:

I checked the errata sheet, no luck.

Any help would be appreciated,
thanks
