DACx_DATnL field descriptions
Field Description
DATA0 DATA0
When the DAC buffer is not enabled, DATA[11:0] controls the output voltage based on the following
formula: V
out
= V
in
* (1 + DACDAT0[11:0])/4096
When the DAC buffer is enabled, DATA is mapped to the 16-word buffer.
36.4.2 DAC Data High Register (DACx_DATnH)
