Functional Description
33.4.6 DAC Control Register 2 (DACx_C2)
Addresses: DAC0_C2 is 400C_C000h base + 23h offset = 400C_C023h
33.5 Functional Description
The 12-bit DAC module can select one of the two reference inputs — DACREF_1 and
DACREF_2 as the DAC reference voltage (V
the module introduction for information on the source for DACREF_1 and DACREF_2.
When the DAC is enabled, it converts the data in DACDAT0[11:0] or the data from the
DAC data buffer to a stepped analog output voltage. The output voltage range is from
