Does anyone know if the BRGH problem has been fixed with the 16C74A? -Ed V. ______________________________ Reply Separator _________________________________ Subject: Re: 16C74 BRGH bug Author: pic microcontroller discussion list at InterNet Date: 6/22/96 6:13 AM Mike Fahrion wrote: > A product has fallen into my lap with a 16C74, using the USART for > asynchronous RX with the BRGH bit set.

Well, I'm using the 16C65, but the same language is used in that part's errata sheet. I was receiving 16-byte packets at 9600 baud (BRGH=1), with bit 8 used as an address flag -- I never tried it without the parity/bit 8. Results observed were: 10-20% of received packets were corrupted. Upon closer examination, a single character within each corrupted packet was found to be corrupted. ----------------------------------------- Frank Latos, Duo Systems Inc. flatos@mich.com -----------------------------------------
