Title:
REGISTER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2016/129149
Kind Code:
A1
Abstract:
Provided is a register circuit the initial value of which is changeable without using a flip-flop having both a set terminal and a reset terminal. The register circuit is provided with: a first flip-flop that changes a first signal from a first value to a second value in response to input of a clock signal; an output control circuit that, when the first signal has the first value, outputs, as a second signal, the initial value of an output signal supplied from an initial value line, and when the first signal has the second value, outputs, as the second signal, an input signal in response to a write signal indicating writing of the input signal; a second flip-flop that latches and outputs the second signal on the basis of the clock signal; and a selector that, when the first signal has the first value, outputs, as the output signal, the initial value, and when the first signal has the second value, outputs, as the output signal, the second signal supplied from the second flip-flop.
