MT F Walk a Bit Test MT F
6.5.6 Walk a Bit Test
CPU32Diag>MT F
MT F performs a walking bit test from start address to stop address. The walking bit test for each
memory location is implemented in the following manner:
• Write out a 32-bit value with only the lower bit set.
• Read it back and verify that the value written equals the one read. Report any errors.
• Shift the 32-bit value to move the bit up one position.
• Repeat the procedure (write, read, and verify) for all 32-bit positions.
EXAMPLE
After the command is entered, the display should appear as follows:
F MT Walk a bit Test ................Running ---------->
If an error is encountered, then the memory location and other related information are
displayed.
F MT Walk a bit Test ................Running ---------->..... FAILED
(error-related information)
If no errors are encountered, then the display appears as follows:
F MT Walk a bit Test ................Running ----------> PASSED

MT G Refresh Test MT G
6.5.7 Refresh Test
CPU32Diag>MT G
MT G performs a refresh test from Start Address to Stop Address. The refresh test has been
implemented in this manner:
1. For each memory location:
• Write out value $FC84B730.
• Verify that the location contains $FC84B730.
• Proceed to next memory location.
2. Delay for 500 milliseconds (1/2 second).
3. For each memory location:
• Verify that the location contains $FC84B730.
• Write out the complement of $FC84B730 ($037B48CF).
• Verify that the location contains $037B48CF.
• Proceed to next memory location.
4. Delay for 500 milliseconds.
5. For each memory location:
• Verify that the location contains $037B48CF.
• Write out value $FC84B730.
• Verify that the location contains $FC84B730.
• Proceed to next memory location.
EXAMPLE
After the command is entered the display should appear as follows:
G MT Refresh Test....................Running ---------->
If an error is encountered, then the memory location and other related information are
displayed.
G MT Refresh Test....................Running ---------->..... FAILED
(error-related information)
If no errors are encountered, then the display appears as follows:
G MT Refresh Test....................Running ----------> PASSED
