Note 1:
Stay within internal 1.2 V reference voltage with given prescaling on AIN pin and do not violate
ADC maximum input voltage (for damage) for a given VCC, e.g. If VCC is 1.8 V can only expose
AIN pin to 2.1 V (VCC+0.3).
Note 2:
Currently, the
Note 3:
ADC input impedance is estimated mean impedance of the ADC (AIN) pins. The tolerance is
+/-20%. The ADC is highly sensitive to the impedance of the source. The ADC (AIN) input
impedance is 200k-600k depending on your ADC gain (prescaling) setting. Normally, when not
sampling, the ADC (AIN) impedance will have very high value and can consider it to be an open
circuit. The moment ADC is sampling, ADC(AIN) impedance is 200k-600k.

nAutoRUN (SIO_28)
Pin 40 (nAutoRUN) is an input, with active low logic. In the development board (DVK-BL600-sx) it is connected
so that the state is driven by the host's DTR output line. nAutoRUN pin needs to be externally held high or low
to select between the two BL600 operating modes:
Self-contained Run mode (nAutoRUN pin held at 0V).
Interactive / Development mode (nAutoRUN pin held at VCC).
