Chapter 36 12-bit Digital-to-Analog Converter (DAC)
DACx_DATnL field descriptions
Description
When the DAC Buffer is not enabled, DATA[11:0] controls the output voltage based on the following
formula. Vout = Vin * (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_DATH)

DATA[11:8]
Description
This read-only field is reserved and always has the value zero.
When the DAC Buffer is not enabled, DATA[11:0] controls the output voltage based on the following
formula. Vout = Vin * (1 + DACDAT0[11:0])/4096
When the DAC Buffer is enabled, DATA[11:0] is mapped to the 16-word buffer.
36.4.3 DAC Status Register (DACx_SR)
If DMA is enabled, the flags can be cleared automatically by DMA when the DMA
request is done. Write zero to a bit to clear it. Writing one has no effect. After reset
DACBFRPTF is set and can be cleared by software, if needed. The flags are set only
when the data buffer status is changed.
Addresses: DAC0_SR is 400C_C000h base + 20h offset = 400C_C020h
