i programmed dsp over the last years but now i have a board with this chip
on it - i'm not able to reprogramm the device, but
i need the dataset for correct setting the filter params etc.
TI has no datasheet because they say the chip is obsolete and therefore i
need information/datasheet for this
low cost chip.
