read as 1 before writing a new command to HACCSAR/HACCSDR. When bit 19 (RW)
of HACCSAR is 0 and TX12_ATOMIC is 1, take the following steps:

3.
Initialize CMDDMT and CMDAMT before first accessing a codec register after HAC
initialization by any reset event.
After making the settings in HACCSDR and HACCSAR, poll CMDDMT and
CMDAMT until they are cleared to 1, and then initialize these bits.
Now the next write to a register is available.
