Address 0x0112 and Address 0x0113 Woofer Right Balance Control Registers (Default: 0x0080, 0x0000)
These two registers control the balance for the right tweeter output.
The balance control words are 28-bit words in twos complement and a 5.23 format. This means there are five bits to the left of the decimal
point of which the most significant bit is the sign bit.

These two registers control the volume for the main channel output.
The volume control words are 28-bit words in twos complement and a 5.23 format. This means there are five bits to the left of the decimal
point of which the most significant bit is the sign bit.

Hold time
These register bits control the hold time for the limiter, which is the time in ms that the limiter
holds the attenuated level after the current input to the limiter function falls below the limiter
threshold.
