Data present at the A and B input registers is latched on the rising edges of CLK A and CLK B respectively. RND, TC, ACC, and SUB controls are latched on the rising edge of the logical OR of CLK A and CLK B. TC specifies the input as two’s complement (TC HIGH) or unsigned magnitude (TC LOW). RND, when HIGH, adds ‘1’ to the most significant bit position of th.
