Description

Checks if the specific instructions/prefixes inhibit Z80 from accepting interrupt request.

It's running long blocks of the particular instruction or prefix bytes for roughly one second, then displays the amount of interrupt handler entries executed during the blocks (should be roughly 50 for non-inhibiting instruction like nop, and near zero for inhibiting instructions).
