Abstract
A counter circuit having a load function which is able to speedily yet stably perform counting operations no matter what kind of value has been loaded. The counter circuit having a load function performs counting operations in synchronization with an input clock signal and is able to count from an arbitrary value upon receiving a count initiation value in synchronization with a load signal. The principal composing elements are: at least three counter circuits 1-1.about.1-N, each of which corresponds to a numerical digit; at least one load value monitor circuit 2-i (wherein i is an integer between 3 and N), which detects whether or not load values of the counter circuits 1 corresponding to lower digits are full count values upon input of the count initiation value in synchronization with the load signal, and delays the output of the load signal by one clock period if a full-count value has been detected; and at least one OR circuit 3-i, which receives an output from load value monitor circuit 2-i and a carry output from counter circuit 1-(i-1), then outputs their logical sum to an ET terminal of counter circuit 1-i.
