; Calculate and keep low 32-bit result: Y32 = M32*X16 >> 32
MOV TL,#0
MOV T,@X16
IMPYL P,XT,@M32
MOVL
Upper 16 bits of the multiplicand register (XT)
Immediate constant value of zero
Load the lower half of the multiplicand register (TL) with zero, leaving the
upper half (T) unchanged:
TL = 0x0000;
T = unchanged;
None
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
; TL = 0
; T = X16
; P = XT * M32 (high 32-bit of result)
@Y32,P ; Store result into Y32
Clear the Lower Half of the XT Register
