Each DAC channel has its own Input register and DAC register. The DAC Register
18
- stores digital code equivalent to the DAC output voltage while the Input Register
19
- acts as a temporary staging register before being passed on the DAC Register. With
20
- the LDAC function, one or more DAC registers could be updated in parallel with
21
- the data held in the Input Register. The DAC registers can also be directly written
22
- to, in which the corresponding output updates immediately without an LDAC.
