SLAS538A – OCTOBER 2007 – REVISED NOVEMBER 2007

The remaining page-1 registers are either reserved registers or are used for setting coefficients for the various

filters in the TLV320AIC34. 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 8 is a list of the page-1 registers, excepting the previously described
