When responses are received, the values will be updated. When <Esc> key is
used, the previous menu will come to the screen. Below is the list of DSP pro-
cessor test faults. Only one fault value is indicated in the DSP processor self-
test message. MCU test results are indicated one by one on the separate lines.

have been passed. MCU test results will be one of the next: No Response, OK,
NOT EXECUTED, FAILED

are from the first failed MCU BUS test. When none of MCU BUS tests has been
