Note: These bits can be written only when the DAC channel is disabled and in Normal operating
mode (when bit ENx=0 and bit CENx=0 in the DAC_CR register). If ENx=1 or CENx=1 the
write operation is ignored.
Bits 31:24
Reserved, must be kept at reset value.
Bits 23:16 TREFRESH2[7:0]: DAC channel2 refresh time (only valid in Sample and hold mode)
Refresh time= (TREFRESH[7:0]) x LSI clock period
Note: This register can be modified only when EN2=0.
These bits are available only on dual-channel DACs. Refer to Section 16.3: DAC
implementation.
Bits 15:8 Reserved, must be kept at reset value.
Bits 7:0 TREFRESH1[7:0]: DAC channel1 refresh time (only valid in Sample and hold mode)
