"CPU Start-up" is 5-10us with a 1MHz system clock (presumably that time reduces at 4MHz or 8MHz ?) That's not quite what the Mid-range manual says about IntRC start-up in the 16Fs of the time, but the M-RM is a few years old now, and the F88 has a much more sophisticated clock block than earlier PICs -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
