6.14.1 x Volume Control
Sets the level of the x Volume Control. Each volume step equals ^6.02/₁₆ dB ~= 0.38 dB. See Section
4.6.5.1 on page 40 for the muting behavior of these volume registers.

6.15.1 INT MODE
Sets the behavior mode of the interrupt registers of the device. In the default configuration, if the interrupt
notification registers are read and any error is found to have occurred since the last clearing of that reg-
ister, the device will automatically set the corresponding mask bit in the appropriate mask register. In the
nondefault configuration, mask bits are not set automatically.

Upon the reading of an error out of the interrupt notification bits, the CS4244 will:
Automatically set the corresponding mask bit.
Not set the corresponding mask bit.
