It doesn't depend on the clock source. It stops executing instructions until it is wakened from sleep by a reset, watchdog timeout, suitable interrupt etc, same as the newer PICs. I don't know if it was different for some of the older PICs, I've never had the need to use 16c5x etc :-) Nigel -- Nigel Orr, Design Engineer nigel@axoninstruments.co.uk Axon Instruments Ltd., Wardes Road,Inverurie,Aberdeenshire,UK,AB51 3TT Tel:+44 1467 622332 Fax:+44 1467 625235 http://www.axoninstruments.co.uk -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
