Definitions

  • the interrupt generator circuit includes a first input to receive an interrupt request signal, a second input to receive an interrupt clear signal, and an output to provide an interrupt input signal synchronized to the interrupt request signal to selectively interrupt the first circuit.
  • the interrupt clear circuit in one example includes an output synchronized to the first clock signal to provide the interrupt clear signal to reset the interrupt generator circuit in response to an acknowledgment signal from the first circuit.
  • the interrupt generator circuit 110 includes an interrupt flag or interrupt generator flip-flop 112, in this case a data or "D" flip- flop that generates the interrupt input signal INT IN according to a synchronized interrupt request signal SET FLAG on a circuit node 111 received from a flip-flop 106.
  • the flip-flop 106 receives the interrupt request signal IR from the node 104 as a data input, and includes a clock input connected to the slow clock node 105.
