For switched systems, well sometimes there is a enable pin on the switcher wich can be used with a time delay cirquit. Im starting to feel baad about the whole issue, im starting to think that this 5v, 3,3v and speed of the io ports are a very bad design error philips have made! A CPU that works at 60Mhz with Io that can do at best 2.5-3Mhz???? I consider this serious crap! With this speed in some applications makes the LPC2106 completely useless!! Reg KD
