3.1.4 TEST State
The DSP Card can be put in an endless SDRAM memory test by setting Switch 1 to ON. This State is indicated
on the LED bar when the top two LEDs are lit.
A pre-defined sequence of memory-tests are performed and indicated on the first 8 LEDs (from bottom up)
similar to the transition from IDLE to PROCESSING. The last of the 8 tests does not end and toggles the
according LED periodically if no error occurred.
Remember that this test will prevent the Card from going into any other State (no booting possible).
