Abstract
A circuit for generating programmable interrupt signals including apparatus for counting the individual rows of signals being displayed by an output display, apparatus for selectively storing a signal indicating a particular row, apparatus for determining when the signal counted by the apparatus for counting the individual rows of signals and the signal stored by the apparatus for selectively storing a signal indicating a particular row are equal, and apparatus for producing an interrupt signal when the signal counted by the apparatus for counting the individual rows of signals and the signal stored by the apparatus for selectively storing a signal indicating a particular row are equal.
