The DAC8B1C module consists of analog and digital sub-blocks.

Data to be converted is written to DACD register. The data can be mapped either to left end or right end
of DACD register by clearing or setting DJM bit of DACC0 register. Also, the data written to DACD can
be a signed or unsigned data depending on DSGN bit of DACC0 register. See
formats. The maximum unsigned data that can be written to DACD register is $FF while the minimum
value is $00. If the data is signed, the maximum value that can be written to DACD is $7F while the
minimum value is $80, where $7F (signed) corresponds to $FF (unsigned) and $80 (signed) corresponds
to $00 (unsigned).
