That's what I mean: a 300 pages datasheet without an index is not a proper datasheet.
And this translated datasheets usually have many errors, some examples:
"12-bit Analog-to-Digital Converter
- 10-bit Resolution, DNL is ±1LSB, INL is ±1.5LSB
- Sampling rate can reach to 5000KSPSat highest resolution"
"the result is written to the ADC Data Registers, and ADIF is set, meanwhile ADIF is cleared"
A good datasheet is already difficult to understand, a bad datasheet is a nightmare.
