Figure 12 · Fully Enumerated Filter I/O Posts
The pinout of Figure 12 is a superset of all possible ports. In every configuration only a subset of these is
used.

width,
COEF_WIDTH
Coefficient input. The coefficients are to be loaded sequentially, one by one.
The coefficients are loaded in a temporary storage. They replace the current
coefficients all at once on COEF_ON signal. This port is enabled only when
reloadable coefficient mode is selected.
COEFI_VALID
In
1
Coefficient valid. Active high. When the signal is active, a coefficient is
loaded into the MAC FIR filter. This port is enabled only when reloadable
coefficient mode is selected.
COEF_ON
In
1
Coefficients on. Active high. Updates the filter coefficients. In Constant
Coefficient mode (COEF_TYPE = 0), the signal replaces the existing filter
