The remaining page-13 registers are either reserved registers or are used for setting coefficients for the various filters in the . Reserved registers must 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 must always be written first, immediately followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both registers must be written in this sequence. is a list of the page-13 registers, excepting the previously described register 0.
