All filters operate in 5-tap filter mode – requiring 5-tap coefficients regardless of the filter usage. For less-than-5 tap filter configurations, coefficients corresponding to the unused taps should be set to 0.
For example, FIR_C0 and FIR_C4 will need to be set to 0x0 for a 3-tap configuration.
For 4-tap configuration, FIR_C0 will need to be set to 0x0.
