Datasheet
16.3.4.11.1 Coefficients and Sample Data Buffers. Each input vector is stored in a cyclic
buffer containing M+1 bytes. Each sample is a 16-bit half-word and the newest sample is
stored in the address that follows the previous sample. The output buffer is a cyclic buffer
that contains N+1 bytes. Each output is a 16-bit half-word and the newest output is stored
in the address that follows the previous one.
16.3.4.11.2 WADD Function Descriptor. The WADD function descriptor bit table is
described below.
