Register Map
For Unipolar signals, ie 0 to +FULL_SCALE_VOLTS, the actual
12 bit DAC0DATA value is obtained from:-
DAC0DATA= (DACVOLT *4096 ) /FULL_SCALE_VOLTS
For Bipolar
+FULL_SCALE_VOLTS, the actual 12 bit DAC0DATA value is
obtained from:-
DAC0DATA=
( DACVOLT*2048 / FULL_SCALE_VOLTAGE ) + 2048

The DAC1 D/A Converter Output Registers.

______________________________________
The DAC1 D/A Converter takes a 12 bit value that is the
digital representation of the required analogue output voltage.
This 12 bit value is written to two adjacent 8 bit, write only,
registers. The lower 8 bits of the 12 bit value are written to the
DAC0LO register. The upper 4 bits of the 12 bit value are
written to lower most 4 bits of the DAC1HI register. The upper
