Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To shift a watch dog timer to a standby mode with no malfunction of the timer by stopping a clock to be supplied that is supplied only when the operation of the timer is stopped by a standby control signal. SOLUTION: When the contents of a reset bit R1 are equal to '1', a reset signal S1 is set at 'High' to reset a counter and to inhibit the input of a clock. Thus, a watchdog timer inhibits its operation. While the signal S1 is kept at 'High', a status register R2 latches the inverted signal of the signal S1 and holds '0' as data. Then a status signal S2 is set at 'Low' and inputted to an OR gate K1. If a standby signal S3 is kept at 'Low' under such conditions, a clock stop signal S4 of the output of the gate K1 is set at 'Low' to fix the output of a clock 'Low' level fixing AND gate K2 at '0' and also fixes the output of a clock 'High' level fixing OR gate K3 at '1'.
