I have a problem with an intel xscale pxa250.
Right now, i try to write the ipl for an customized board.
I setup up a lot of registers and after I try to clear the RDH - bit in the
PSSR - register the system will hang after a while.
If i am not clearing the bit the ipl and startupcode works fine, but
I can not read from external hardware.

Two things come to mind - you should probably be clearing the PH bit
as well as the RDH bit, and second, remember that these bits are cleared
by writing a 1 (not 0) to them.

I already noticed that I have write an 1 to set bit for clearing.
I figured out that one configuration register was not setup probably.
Now it works fine, thank you for try to help me.
