Minimum value (left justified)
When the DAC is in automatic mode (CTRL[AUTO] = 1), the minimum value contained in this register will
act as the lower range limit during automatic waveform generation. This register is not used during normal
mode operation, but can still be written to and read from. Please refer to the chip data sheet for limitations
on the low end voltage output of the DAC.
NOTE: If DAC input data is less than MINVAL, output will be limited to MINVAL during automatic
This read-only bitfield is reserved and always has the value zero.
