6.5 MEMORY TESTS (MT)

The memory tests are a series of diagnostics which verify random access memory (read/write)
that may or may not reside on the M68300EVS evaluation system. Default is the BCC on-board
RAM. To test off-board RAM, change Start and Stop Addresses per MT B and MT C as
described in the following paragraphs. Memory tests are listed in Table 6-2.
If one or more memory tests are attempted at an address where there is no
memory, a bus error message appears, giving the details of the problem.
