ABSTRACT:
A large scale integrated circuit central processing unit for calculator applications generally includes at least one information storage register and means for generating a word time signal designating the effective digit capacity of the information storage register. An additional external terminal is provided for the package of the integrated circuit to accept control signals applied thereto which are effective to modify the pulse width of the word time signal. Application of the control signals to the external terminal renders the word time signal generating means operative to enable the modification in the pulse width of the word time signal and hence in the effective digit capacity of the storage register.
