5.2.9 Maximum Value Register (DAC_MAXVAL [FORMAT=1])
Address: DAC_MAXVAL [FORMAT=1] – F1A0h base + 4h offset = F1A4h
5.3 Functional Description
5.3.1 Conversion modes
This DAC supports two conversion modes: asynchronous conversion and synchronous
conversion.
5.3.1.1 Asynchronous conversion mode
Data can be immediately presented to the DAC and converted to an analog output when it
is written to the DAC buffered data register.

Maximum value (left justified)
When the DAC is in automatic mode (CTRL[AUTO] = 1), the maximum value contained in this register will
act as the upper 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 high end voltage output of the DAC.
NOTE: If DAC input data is greater than MAXVAL, output will be limited to MAXVAL during automatic
This read-only bitfield is reserved and always has the value zero.
