Set Bus Data Width (Mt D) - Motorola M68CPU32BUG User Manual

MT D
6.5.4 Set Bus Data Width
CPU32Diag>MT D [new value: 0 for 16, 1 for 32]
MT D selects either 16-bit or 32-bit bus data accesses during the M68CPU32Bug MT memory
tests. The width is selected by entering zero for 16 bits or one for 32 bits.
EXAMPLE
If the user supplied the optional new value, then the display appears as follows:
CPU32Diag>MT D [new value]<CR>
Bus Width (32=1/16=0) =<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.
CPU32Diag>MT D<CR>
Bus Width (32=1/16=0) =<current value> ?[new value]< CR>
Bus Width (32=1/16=0) =<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 D<CR>
Bus Width (32=1/16=0) =<current value> ?< CR>
Bus Width (32=1/16=0) =<current value>
