DIAGNOSTIC FIRMWARE GUIDE
M68CPU32BUG/D REV 1 6-14
MT B Set Start Address MT B
6.5.2 Set Start Address
CPU32Diag>MT B [new value]
MT B allows the user to select the start address used by all of the memory tests. For the
MVME332, it is suggested that address $00003000 be used. Other addresses may be used, but
extreme caution should be used when attempting to test memory below this address.
EXAMPLE
If the user supplied the optional new value, then the display appears as follows:
CPU32Diag>MT B [new value]<CR>
Start Addr.=<new value>
CPU32Diag>
If a new value was not specified by the user, then the old value is displayed and the user
is allowed to enter a new value.
NOTE
The default is Start Addr.=00003000, which is for on-board RAM.
CPU32Diag>MT B<CR>
Start Addr.=<current value> ?[new value]<CR>
Start Addr.=<new value>
CPU32Diag>
This command may be used to display the current value without changing it by pressing a
carriage return <CR> without entering the new value.
CPU32Diag>MT B<CR>
Start Addr.=<current value> ?<CR>
Start Addr.=<current value>
CPU32Diag>
NOTE
If a new value is specified, it is truncated to a longword boundary
and, if greater than the value of the stop address, replaces the stop
address. The start address is never allowed higher in memory than
the stop address. These changes occur before another command is
processed by the monitor.
