DIAGNOSTIC FIRMWARE GUIDE
M68CPU32BUG/D REV 1 6-3
6.2.7 Stop-On-Error Mode (SE)
Use the stop-on-error mode (SE) to halt a test at the point where an error is detected. Enter SE
then the test mnemonic to stop on errors encountered during the test.
6.2.8 Loop-Continue Mode (LC)
Use loop-continue mode (LC) to endlessly repeat a test or series of tests. This command repeats
testing of everything on the command line. To terminate the loop, press the BREAK key on the
diagnostic video display terminal. Certain tests disable the BREAK key interrupt, so pressing the
ABORT or RESET switches of the M68300PFB platform board may become necessary.
EXAMPLE
CPU32Diag>LC ST<CR> Repeats self test (ST) command to continuously test the
system.
6.2.9 Non-Verbose Mode (NV)
The diagnostics display a substantial number of error messages when an error is detected. Non-
verbose mode (NV) suppresses all messages except PASSED or FAILED. At the prompt enter
NV, the test name, and <CR>. NV ST MT causes the monitor to run the MT self-test, but show
only the names of the sub-tests and the results (pass/fail).
6.2.10 Display Error Counters (DE)
Each test in the diagnostic monitor has a dedicated error counter. As errors are encountered in a
particular test, its error counter is incremented. If one were to run a self-test or a series of tests,
the test results could be determined by examining the error counters. Entering DE, the test name,
and a <CR> displays the results of a particular test. Only nonzero values are displayed.
6.2.11 Clear (Zero) Error Counters (ZE)
The error counters, at start-up, initialize to a value of zero, but it may be necessary to reset them
to zero after errors have accumulated. The ZE command resets all error counters to zero. The
error counters can be individually reset by entering the specific test name following the
command. Example: ZE CPU A clears the error counter associated with CPU A.
6.2.12 Display Pass Count (DP)
A count of the number of passes in loop-continue mode is kept by the monitor. This count is
displayed with other information at the conclusion of each pass. To display this information
without using LC, enter DP.
