23-0 LAST_CONV ADC Input Channel's Last Converted Value.
This register indicates whether the last converted value for a particular input channel was lower or
higher than the mid-point of the reference voltage. In other words, this register acts as a digital
input register and can be read by the application to determine the digital level at the input pins.
This data is only valid for an input channel if it has been converted at least once.
Any operation mode read for each bit of this register:
0 A level lower than the midpoint reference voltage was measured at the last conversion for this
channel.
1 A level higher than or equal to the midpoint reference voltage was measured at the last conversion
for this channel.
