and interrupts overhead is impacting the performance of the Engine. If the Engine process rate drops
significantly, its ability to detect motion can be significantly reduced. This value is typically used at the
application development stage. This number gives an indication of how much CPU time the Engine
is receiving. Higher numbers are better. Generally, if the process rate drops below 0080h, the ability
