Windowing Strobes Program Example

The following example illustrates a method to use local logic to perform a windowing strobe

function. The example ignores the strobe command unless the current motor position is inside the

window (Actual Position > 4000 but less than 5000). If the motor position is inside the

aforementioned window, the first strobe occurrence causes the current motor position to be

captured within the strobe register. The application is shown pictorially in Figure 11-3.
