To place the off-chip codec device into the power-down mode, write 1 to bit 12 of the register
index 26 in the off-chip codec via the HAC. When entering the power-down mode, the off-chip
codec stops HAC_BITCLK and suspends the normal operation. The off-chip codec acts in the
same manner at power-on. To resume the normal operation, perform a cold reset or a warm reset
on the off-chip codec.
