Description
Reserved
These bits are always read as 0. The write value should
always be 0.
0: The HAC-connected codec is not ready.
1: The HAC-connected codec is ready.
Reserved
These bits are always read as 0. Write prohibited.
HAC Cold Reset
Use a cold reset only after power-on, or only to exit
from the power-down mode by the power-down
command.
[Write]
0: Always write 0 to this bit before writing 1 again.
1: Performs a cold reset on the HAC-connected codec.
[Read]
Always read as 0.
