Post by thread:Can you disable or reduce the 18ms delay when waki

I am using the PIC for the first time. I am desigining a home automation product for my graduate project. Is their a way to reduce or eliminate the 18ms startup delay when awaking the PIC out of sleep. I am refering to the 16C5X series. My circuit works by sensing passive infrared radiation to detect human presence. A low pulse on the MCLR pin awakens the PIC out of sleep mode and the program starts about 18ms or so later. The problem... alot can happen in 18ms. I would think if I use an RC oscillator instead of a crystal variant the PIC would'nt need this time. I have searched the data book and have not been able to find a way to reduce or eliminate this delay. I would appreciate any help. Thanks. By the way as a service to others, I am currently trying to start a PIC newsgroup on USERNET and working on an archive of mailing list posts to be integrated with a WWW page and search machine.
