Bit [7:0] : Data [7:0] 8-bit data value is the high order result of the multiply function
Bit [7:0] : Data [7:0] 8-bit data value is the low order result of the multiply function
Bit [7:0] : Data [7:0]
8-bit data value when read is the next to lowest order result of the multiply/accumulate function
8-bit data value when written is the X multiplier input to the multiply/accumulate function
Bit [7:0] : Data [7:0]
8-bit data value when read is the lowest order result of the multiply/accumulate function
8-bit data value when written is the Y multiplier input to the multiply/accumulate function
