:
Z-MULT (zero flag)
V-MULT (overflow flag)
The N-MULT, Z-MULT, and V-MULT flags are not modified by switching between
saturating and non-saturating modes, or by execution of a multiply instruction (MULXU or
MULXS).

Set when register MACL is cleared to 0 by execution of a MAC
instruction
Cleared when register MACL is not cleared to 0 by execution of a
MAC instruction
Set when registers MACH and MACL are both cleared to 0 by
execution of a MAC instruction
Cleared when register MACH or MACL is not cleared to 0 by
execution of a MAC instruction
Set when the result of the MAC instruction overflows the range
from H'80000000 (minimum) to H'7FFFFFFF (maximum)
