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: Current production
smart
BASIC runtime engine firmware (v1.1.50.0) allows only 10-bit mode.

nAutoRUN (SIO_28)

I
Input with active low logic.
Operating mode selected by nAutoRun pin status:
Low (0V), then runs $autorun$ if it exists;
High (VCC) then run via at+run (and “file name” of
smart
BASIC application.
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).
smart
BASIC runtime engine firmware checks for the status of nAutoRUN during power-up or reset. If it is low
and if there is a
smart
BASIC application named $autorun$ then the
smart
BASIC runtime engine executes the
application automatically; hence the name
self-contained run mode
.
