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.

MT C Set Stop Address MT C
6.5.3 Set Stop Address
CPU32Diag>MT C [new value]
MT C allows the user to select the stop address used by all of the memory tests. The stop address
is the address where testing terminates, so the stop address must be set to the last address +1.
EXAMPLE
If the user supplied the optional new value, then the display appears as follows:
CPU32Diag>MT C [new value]<CR>
Stop 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 Stop Addr.=00010000, which is the end of on-board
RAM.
CPU32Diag>MT C
Stop Addr.=<current value> ?[new value]<CR>
Stop 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 C
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 less than the value of the start address, is replaced by the
start address. The stop address is never allowed to be lower in
memory than the start address. These changes occur before another
command is processed by the monitor.
