The DAC can be output to the DACOUT pin by setting
the DACOE bit of the DACCON0 register to ‘1’. Selecting
the DAC reference voltage for output on the DACOUT
pin automatically overrides the digital output buffer and

Reading the DACOUT pin when it has been configured
for DAC reference voltage output will always return a ‘0’.
Due to the limited current drive capability, a buffer must
be used on the DAC voltage reference output for
external connections to DACOUT.
