3 x 3 Matrix Multiplier (Mode 00)
This mode utilizes all six input and output ports in the basic
configuration to realize a "triple dot product", in which each
output is the sum of all three input words in that column
multiplied by the appropriate stored coefficients. The three
corresponding sums of products are available at the outputs
five clock cycles after the input data are latched, and three
new data words half-LSB rounded to 12 bits are then avail-
able every clock cycle.
