recommended to write the MCOMP register during the Z interrupt routine to avoid any spurious
comparison as several consecutive C
Note that two different simulated events can be used in the same step (like D
Note also that for more precision, it is recommended to use the value captured from the preceding
hardware event to compute the value used to generate simulated events.

1. If the SC bit is set during Z event interrupt, then the 8*8 bit hardware multiplication result must be overwritten in the
MCOMP register. Otherwise, when the SC bit is set, the result of the multiplication is not taken into account after a Z event.
