Description
not used
For debugging purposes, the DAC clock polarity can be
inverted.
If active, the clock PLL for DAC sampling can be
bypassed. Then, the crystal output is directly taken for
DAC sampling.
For accuracy, one external resistor connected to
pin RSET and board ground controls the bias current.
Moreover, B_REF permits to adjust this bias current from
binary.
When HIGH, PD_DA_REF sets the reference module
into its Power-down mode.
