† _{The maximum clock frequency is independent of the internal programmed configuration. If an output is fed back externally to an input, the}
maximum clock frequency must be calculated.
‡ _{The C-array is the single sum term that is complemented and fed back to the AND array.}
§ _{After Preset goes inactive, normal clocking resumes on the first low-to-high clock transition.}
