Abstract
Disclosed is a system and method for testing a dual mode interface. The dual mode interface includes a first strobe circuit and a second strobe circuit configured to be operable during a first operational mode and inoperable during a second operational mode. The dual mode interface also includes a first data circuit and a second data circuit configured to be operable during the first operational mode and the second operational mode. The dual mode interface also includes a signal line connecting an output of the second strobe circuit with an input of the first strobe circuit and a switch element configured to activate said signal line in response to receipt of a test signal.
