Header J303
Header J303 is primarily dedicated to connecting the external analogue multiplexer hardware which
allows expansion of up to 8 additional ADC channels. For multiplexer channels decoding, MA[x] signals
are used. Multiplexed channels are connected to the ADC0_X[3] input. In other cases, the header J303 pins
can be used as general purpose I/O. See a detailed description in
Table 14
