I make my own ADuC845 pcb base on  Eval-ADuC845QS schematic and got following problems:


- current is 2 times higher compare to Eval board

- DAC 400Hz example works fine with 5.7V supply  but to program it I need 6.7V

- I type simple program utilize timers, interputs to generate a waveform on DAC but it generate only one period after power up? on Eval works fine.


Could you please advice where I could make a error?
