DACI offset correction. The offset is measured in DAC LSBs. If enabled in config30
writing to this register causes an auto-sync to be generated. This loads the values of
the QMC offset registers (config8-config9) into the offset block at the same time.
When updating the offset values config8 should be written last. Programming
config9 will not affect the offset setting.

12:0 qmc_offsetQ(12:0)
Function
When the sync to the FIFO occurs, this is the value loaded into the FIFO read pointer. With
this value the initial difference between write and read pointers can be controlled. This may
be helpful in syncing multiple chips or controlling the delay through the device.
DACQ offset correction. The offset is measured in DAC LSBs.
