ABSTRACT:
A multi-digit counter circuit performs both successive data production function and non-successive data production. Successive data is produced by an increment or decrement operation according to a first carry (borrow) signal. Non-successive data is produced by a control circuit which applies a second carry (borrow) signal independently of the first carry (borrow) signal to an arbitrary selected digit or digits. The arbitrary digit is designated according to the distance between the preceding data and the following data to be produced.
