CPU Cycles required:
Description:
Perform a 16-bit move operation from port-X to the A-
register.
The port-X contents are unchanged.
The previous contents of A-register are overwritten
and lost.
The port-X can be any of the CPU ports.
PC is incremented once to point to the next instruction
in program memory.
Two’s-complement data format is preserved.
No branching occurs.
No other registers are affected.

Op-code:
Operation:
CPU Cycles required:
Description:
Perform a 16-bit by 16-bit arithmetic multiplication of
the M-register and the N-register producing a 32-bit
result. The 32-bit result is stored in two 16-bit registers;
the A-register receives the most significant word of the
result and the M-register receives the least significant
word of the result.
The A-register must be cleared to zero (CLX A) before
executing the MLT instruction. The previous contents of
the A-register are overwritten and lost.
The previous contents of the M-register are overwritten
and lost.
The contents of the N-register are not altered.
The register op code must be 3h.
PC is incremented once to point to the next instruction
in program memory.
Two’s-complement data format is preserved.
No branching occurs.
No other registers are affected.
