Because the Sum-In and Sum-Out are truncated by 6 bits rel-
ative to the external accumulation pipeline, the TMC2243
rounds internally by adding 2
-13
to each emerging sum of
products, effecting half-LSB rounding relative to the output
format. The chip internally utilizes all lower-order bits,
to 2
.
