DADRy registers are 16-bit readable/writable registers, which store data to which D/A conversion is to be performed.
Whenever an analog output is enabled, the values in DADRy are converted and output to the analog output pins.
10-bit data can be relocated by setting the DPSEL bit in DADPR.
Bits "
" are always read as 0. The write value should always be 0.
