Description
coefficients with the new set of coefficients pointed by the input COEF_SEL.
In Reloadable Coefficient mode (COEF_TYPE = 1), the signal makes the
filter start using coefficients recently loaded in the auxiliary page.
COEF_SEL

Coefficient set selector. Identifies the pre-programmed fixed coefficient set to
be activated and used as the filter coefficients. This port is enabled only
when Multiple Coefficients mode is selected.

Asynchronous reset. Active low. Resets all internal registers. The signal is
expected to follow the FPGA power-on.

Synchronous reset. Active low. Resets all internal registers.
Data output. The filtered data appear on this port. It is a full precision output.
For example, at 12-bit data, 15-bit coefficients, and 150 taps, the output
width = 12 + 15 + ceil(log2150) = 12 + 15 + 8 = 35 bits.
Output data valid. Active high. Indicates that a new output data sample is
present at the FIRO port
modes. Figure 15 shows Multiple Coefficients mode.
