DAVAIL
Data Available Bit—This bit indicates whether
conversion output is available. If this bit is set, the
ADC is finished with the last conversion and the result
can be read from the FIFO. This bit is cleared if the
FIFO is empty.
Writing to the ADCLR Register sets this bit on the
PC-LPM-16 only. You need a FIFO (low and high
bytes) reading to completely empty the PC-LPM-16
FIFO. On the PC-LPM-16PnP, the DAVAIL bit
always exactly represents whether data is in the FIFO.
