ds89c450 uart timer tmod
Yep... thx for your post... ive read the errata already before... in my case (now i use a 24Mhz xtal) the maxBaud (acc. to this formula) would be ~20kbaud. But the matching to one of the timer-reloads was the problem. I dont know, why they had used only a few possible reloadvalues (acc. to the datasheet), so that the matching is only given for some baudrates...
I use now 2400 Baud (xtal: 24Mhz), and it works - slow, but it works...
Thx again,
bye
Daniel
