Other Parts Discussed in Thread: DAC3484
Depending on the reseverd Bit in config1 bit8, I get different behavioures. But both give not the expected behavioure.
If I let the reserved bit in config_1 in default state:
The IOTEST works, but databit D12 and D3 are inverted. If I invert these bits in my data interface the IOTEST gives a error free output.
If I clear the reserved bit in config_1 (bit8) as recommended in data sheet:
The IOTEST gives always the same error pattern in config_4. I'm not able to clear the register.
The strange thing is; the DAC output seems O.K. I can change the parameter of both DAC channels as expected.
What can that be?
