BUSY: (r) set to 1 if a conversion is running. Note that the flag is set at the effective start of the conversion. Since the ADC is
generally synchronized on a lower frequency clock than the CPU, there might be a small delay (max. 1 cycle of the ADC
sampling frequency) between the writing of the START or CONT bits and the appearance of BUSY flag.
DEF: (w) sets all values to their defaults (PGA disabled, max speed, nominal modulator bias current, 2 elementary
conversions, over-sampling rate of 32) and starts a new conversion without waiting the end of the preceding one.
AMUX(4:0): (rw) AMUX[4] sets the mode (0
AMUX(3) sets the sign (0
VMUX: (rw) sets the differential reference channel (0
(r = read; w = write; rw = read & write)
straight, 1
cross) AMUX[2:0] sets the channel.
4 differential inputs, 1
R(1) and R(0), 1
16-7
R(3) and R(2)).
7 inputs with A(0) = common reference)
