This sounds like another classic CCS bug to me. Several times I have found that #fuses bits work backwards in some of their releases, right now I have a project for the 'F73 that must use "NOPUT" to *enable* the power up timer. A sheepish tech at CCS explained that they are working on this after I wasted a couple of hours pulling out my hair.. Try enabling your WDT, I'll bet the WDT will then turn off. Or else, upgrade to the version du jour. -- Lawrence Lile Olin Lathrop Sent by: pic microcontroller discussion list 08/28/02 11:57 AM Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: Subject: Re: [PIC]:problem with Watch-Dog > Yes, but fiddling with the PSA bit can cause an unintended WDT reset even > if it's disabled, apparently. I find that *very* hard to believe. Do you have any solid evidence to support this belief? ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com#nomail Going offline?
