Abstract: An electronic circuit system has at least three macro circuits and a plurality of signal lines for connecting the macro circuits to one another into a loop. Each of the macro circuits includes a logic circuit and a memory circuit and has a plurality of input terminals and a plurality of output terminals. Signals are transmitted through the loop in a single specified direction in synchronization with a clock signal. Each of the macro circuits receives the signals at the input terminals thereof, accepts the signals if the signals are destined for the macro circuit, and transfers the signals to the output terminals thereof if the signals are not destined for the macro circuit. Even if the macro circuits simultaneously transmit signals, the electronic circuit system transmits the signals in the specified direction through the loop in synchronization with the clock signal up to destination macro circuits.

Abstract: A protection method for preventing battery cells from over-discharging and being overcharged, a control circuit, and a battery unit are provided. In the protection method, when a set signal “1” is supplied to a set terminal, a flip-flop outputs “1”. The gate of a discharge control FET then becomes “1”, so that the discharge control FET is OFF regardless of a discharge control signal supplied from a voltage monitor circuit. When a reset signal “1” is supplied to a reset terminal, the flip-flop outputs “0”. The discharge control FET is then switched on and off in accordance with the output of a discharge control circuit of the voltage monitor circuit. In this manner, battery cells connected to an electronic device do not over-discharge, even when they are left unused for a long period of time. Thus, the battery unit can be prevented from deteriorating and shortening the life thereof.
