Se rapò a divizyon sa a vann san preskripsyon mete nan nivo yo vòltaj nan entrain D0-D3 (Pins 15-18). Pou egzanp, lè D0-D3, yo tout ki ba, kontwa an pwogramasyon divize pa 877. Konsa, si osilator a RF ap kouri nan 87.7MHz, pwodiksyon an divize soti nan kontwa an yo pral 100kHz ak sa a alimèt frekans lan divize desann soti nan osilator a 7.6MHz kristal (sètadi, 7.6MHz divize pa 4 divize pa 19).

The division ratio of this counter is set by the voltage levels at inputs D0-D3 (pins 15-18). For example, when D0-D3 are all low, the programmable counter divides by 877. Thus, if the RF oscillator is running at 87.7MHz, the divided output from the counter will be 100kHz and this matches the frequency divided down from the 7.6MHz crystal oscillator (ie, 7.6MHz divided by 4 divided by 19).
