The remaining page 4 registers are either reserved registers or are used for setting coefficients for the various
filters in the processing blocks. Reserved registers should not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient are
interpreted as a 2s-complement integer, with possible values ranging from –32,768 to 32,767. When
programming any coefficient value for a filter, the MSB register should always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both registers
should be written in this sequence. Table 13 is a list of the page 4 registers, excepting the previously described
register 0.
