摘要:
An integrated circuit device includes a programmable logic block, a monitoring input, a condition-sensing circuit coupled to the monitoring input and configured to generate a condition-sensed signal at an output in response to sensing a condition at the monitoring input, a first digital input, a first digital output, and a gating circuit configured in the programmable logic block and coupled between the first digital input and the first digital output. The gating circuit has a gating input coupled to the condition-sensing circuit and generates an output. The output is related to an input state of the first digital input in the absence of the condition-sensed signal and assumes an override state in the presence of the condition-sensed signal.
