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 (MSB) is the
integer part and bytes 1 and 0 are the fractional part.
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 (MSB) is the integer part; the second nibble of byte 2 and bytes 1 and 0 are the fractional part.
