Hello: I have an extrange problem with processor module PCM18XC1 and the usart. Using interrupts in continous reception mode sometimes I miss a character, but overrun error bit is never set. I don't miss any character when I use PCM18XA0 and the same code. Any ideas? -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
