Abstract
One embodiment of the present application includes a microcontroller () that has an embedded memory (), a programmable processor (), and a test interface (). The memory () is accessible through the test interface (). In response to resetting this microcontroller (), a counter is started and the test interface () is initially set to a disabled state while an initiation program is executed. The test interface () is changed to an enabled state—such that access to the embedded memory () is permitted through it—when the counter reaches a predefined value unless the microcontroller () executes programming code before the predefined value is reached to provide the disabled state during subsequent microcontroller () operation.
