Forget the RTC.  It is only useful when the system has been initialized

I am thinking of using an LPC22xx as a single chip micro in an

be used to count external pulses, encoder signal, which pin(s) can be

The LPC2xxx's supposedly have a built in RTC?  Anyone got any info on 
connecting a battery or super cap to maintain the RTC contents during 
power down?
