; Calculate using 16-bit multiply:
; Y = (X0*C0) >> 2) + (X1*C1 >> 2) + (X2*C2 >> 2)
; X2 = X1
; X1 = X0

Addressing mode (see Chapter 5)
Upper 16 bits of the multiplicand register (XT)
Store the 16-bit T register contents into the location pointed to by the "loc16"
addressing mode:
[loc16] = T;
If (loc16 = @AX) and bit 15 of the AX register is 1, then the N bit is set;
otherwise, N is cleared.
If (loc16 = @AX) and the value of AX after the load is zero, then the Z bit is
set; otherwise Z is cleared.
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
