The volume value is a 4.16 coefficient. In order to transmit it over I2C, it is necessary to separate the value into three
bytes. Byte 2 is the integer part and bytes 1 and 0 are the fractional parts.
The mixer gain values and biquad coefficients are 4.20 coefficients. In order to transmit them over I2C, it is necessary
to separate the value into three bytes. The first nibble of byte 2 is the integer part and the second nibble of byte 2 and
bytes 1 and 0 being the fractional parts.
