D25

Use this command to copy memory from one memory region to a writeable memory
region.

It requires three hexadecimal quantities, which define the:
•  source address
•  destination address, and
•  number of bytes to transfer

Below is usage and syntax information for this command

m from_addr to_addr num_bytes

None

from_addr

=  start address of the source region in
    hexadecimal

to_addr

=  start address of the destination in hexadecimal

num_bytes

=  size in bytes (octets), hexadecimal, of the
    region to move

Type m 200000 200400 200 and press 

ENTER

.

Results: This copies the RAM memory region 200000 up to

200200 to the region 200400 up to 200600.

The system displays the prompt when it completes
this instruction.

An attempt to move to EPROM or non-existent memory will
result in a bus error.

You can modify systems with FLASH EPROM such as the
D25 and CCUME using this command.
