7:0

qmc_offseta(7:0)

Lower 8 bits of the DAC A offset correction. The offset is measured in

0x00

DAC LSBs. Writing this register causes an autosync to be

generated. This loads the values of all four qmc_offset registers

(CONFIG20-CONFIG23) into the offset block at the same time. When

updating the offset values CONFIG20 should be written last.

Programming any of the other three registers will not affect the

offset setting.
