to this function. One contains a coefficient base address, five sets of three store the values
of the 24-bit coefficients to be written or that were read, and one contains bits used to
control the write/read of the coefficient(s) to/from RAM.
The read and write operation on RAM coefficients works only if LRCKI (pin 29) is switching.
