Abstract

PURPOSE:To increase the degree of integration by securing such a constitution that can be divided into the high-speed action part and the low-speed action part and then constituting the low-speed action part with the circuit featuring a high degree of integration. CONSTITUTION:The 2-mode prescaler PS1 consists of the counter the counter number of which changes to P or P+1 by the mode switch signal supplied from FF5. The output of PS1 is divided through programable counter PC2, and the count number is controlled by output Q1-Qn of code converter CC3. CC3 generates code output Q1-Qn to be supplied to PC2 with reception of code input P1-Pn plus the output of FF5, and output Q1-Qn change by the output of FF5. Thus, the count number of PC2 is set to N1 or N2 by the output of FF5 even with the same code input Q1-Qn. In such system, PS1, FF4 and 5 are formed with the high-logic circuits, and PC2 and CC3 are formed with the low-logic circuits respectively.
