A/D Clear Register
The ADC can be reset by writing to this register. This operation clears the FIFO and loads the
last conversion value into the FIFO. All error bits in the Status Register are cleared as well.
Notice that the FIFO contains one data word after reset, so two consecutive FIFO readings are
necessary after reset to empty the FIFO. The data that is read should be ignored.
Address: Base address + 08 (hex)
