In all modes except Mode 00, the x port and four bits
of the Y output port are reconfigured as the 16-bit
registered Cascade Input port CASIN
presented to this input will be added to the weighted
sums of the data words which were presented to the
input ports (A, B and C).
In the matrix multiply mode, data are available at the
12-bit registered output ports X, Y AND Z t
