Dear Gilles, I have configured TC0 as IPIPE usage and would like to use the TC1 as real-time interrupt. I have observed that TC1 is not generated its interrupt continuously if it is configured as RC compare trigger with "Software Trigger" (Same as what TC0 is configured). Is this AT91RM9200 Errata? Or I was doing something wrong?
Please advice. Thanks regards, chun yeow On 8/15/07, Yeoh Chun Yeow <[EMAIL PROTECTED]> wrote: > > Dear Gilles, > > Sorry, it's my own mistake.
