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
