Description
Multiply the unsigned 16-bit content of the T register by the unsigned 16-bit
content of the location pointed to by the “loc16” addressing mode and store
the 32-bit results in the ACC register:
ACC = unsigned T * unsigned [loc16];
Flags and
Modes
Z
After the operation, the Z flag is set if the ACC is zero, else Z is cleared.
N
After the operation, the N flag is set if bit 31 of the ACC is 1, else N is cleared.
Repeat
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
; Calculate unsigned using 16-bit multiply:
; Y32 = Y32 + X16*M16
MOV T,@X16
; T = X16
MPYU ACC,T,@M16
; ACC = T * M16
ADDL @Y32,ACC
; Y32 = Y32 + ACC
