This test enables testing of the connectivity between the DLPC230-Q1 and the DMD socket. This test cannot be used during operation. Each pin or differential pair for the DMD high speed interface, low speed interface, DEN_ARSTZ, and DMD reset voltages can be set high or low for testing. These signals can be check by test equipment such as multimeters, oscilloscopes, or other probes to ensure connectivity between the DMD socket and DLPC230S-Q1.
