Abstract:
1. A component of an electronic circuit, the component comprising: a node selectively configurable as an output node for providing an output signal to an external component or as an input node for providing an input signal to an internal component; a capacitor selectively couplable to the node to influence the time for the node to transition between a low state and a high state; and a timer for measuring the time for the node to transition between a low state and a high state to provide a first information input signal, the state of the first information signal depending on the time for the node to transition between the low state and the high state and being indicative of a first information; a first input node and a second input node, wherein receiving a write command at the node enables a test mode operation of the circuit component, and, during the test mode operation, the first input node is operable as a serial input, the second input node is operable as a capture node, and the node functions as a test mode serial output node.
