Pressing the numeric key 1 from the test mode menu selects the D-RAM tests. D-RAM Test 1
writes data to the entire D-RAM region and reads it out to check that operations are correct.
D-RAM Test 2 just reads data at high speed. This test can be used to check operations when
optional memory has been added.
