GENERAL DESCRIPTION
7A. There are four operating modes, timer, divide-by-n, divide-by-10 000 and master preset, which are defined by the mode select inputs (Ka to Kc) and the latch enable input (LE) as shown in the Function table. The complete counter consists of a first counting stage, an intermediate counting stage and a fifth counting stage. The first counter stage consists of four independent flip-flops. Depending on the divide-by-mode, at least one flip-flop is placed at the input of the intermediate stage (the remaining flip-flops are placed at the fifth stage with a place value of thousands).
