15.3 Operation of Multiplier
reading the MULOH and MULOL registers after waiting for 1 clock. The result can also be obtained after 1 clock or
more has elapsed, even when fixing either of MULA or MULB and rewrite the other of these. The result can be read
without problem, regardless of

The result of the multiplication can be obtained by storing the values in the MULA and MULB registers and then
