Title: Watchdog interruption circuit
Inventor: MORI TADAYOSHI
IPC: G06F11/30
Filed: 1990-11-21
Abstract: PURPOSE:To make it unnecessary to use an output terminal for resetting a watchdog(WD) by providing a WD interruption input terminal with an output function for canceling a WD interruption request signal. CONSTITUTION:When the input level of an output transistor(TR) 3 is turned to a high level and the TR 3 is turned on, the output voltage of a time constant circuit 4 is turned to a ground level, and then when the input level of the TR 3 is turned to a low level, the circuit 4 increases its output level and the level of an interruption input terminal 2 is increased. If the input level of the TR 3 is not turned to the high level within a fixed time, the input level of the terminal 2 exceeds the threshold level of an interruption input buffer 1 and the output of the buffer 1 is activated, generating an interruption request. Thus WD operation is executed only by one terminal.
