Abstract
PURPOSE:To omit the input of a clock required for a resetting action to be done before a scanning operation by producing a pulse to reset a latch circuit group at the rise of a scanning action carried out by an access address. CONSTITUTION:A pulse generating circuit 14 produces a pulse in place of a clock at the rise of a scanning action and an address secondary latch circuit group 7 is reset. At the same time, the output of an adder 8 is applied as a write/read address together with the data on a selector group 10 added as the input data. The word value 0 of a register file is read out with input of a 1st clock used for scanning and written with a shift given to a higher position by a bit. While the data supplied in a scan-in mode is written into the lowest rank bit. Hereafter said word value is added by 1 via the adder 8 for each input of a clock and then successively shifted. Thus a scanning action is carried out.
