The Microchip pdf for the 16c73a advises against running async comms with BRGH=1 as it may be unreliable. I want to use the '73a with a 4Mhz clock at 9600 Baud. Acording to table 12-4 this isn't possible and table 12-5 doesn't recommend it ! Am I missing something ? The 1995/1996 databook doesn't contain any such warnings !!?? I looked for an answer in a couple of Pic FAQ areas but found nothing. BTW, where is the best place to search for specific Pic topics ? Thanks guys... ______________________________________ Dave Duffy, Audio Visual Devices 8/9-11 Trade Street Cleveland Qld 4163, Australia Ph: +61 7 38210362 Fax: +61 7 38210281 E-mail: AVD@mailbox.uq.edu.au ______________________________________
