Abstract
A continuity test mode circuit in an integrated circuit device having a means for switching between a continuity test mode and a normal operating mode. The test mode is characterized by one or more input pins being in direct electrical connection with one or more output pins to enable the pins and the chip packaging and chip socket and circuit board to be tested for continuity. In normal operating mode, the operation of the chip is not affected by the test mode circuitry. The continuity test mode circuit allows for testing of device-socket and/or device-board continuity in order to ensure accurate testing and programming of the device.
