DUMP Command
Purpose:
To display the contents of memory in hexadecimal
Format:
[(display start address)].[(display end address)]
Remarks:
If the carriage return
↵
is input by itself, eight bytes of data, starting from the base
address will be displayed (refer to example 2.)
If an address is entered preceded by a dot, e.g., “.3000”, data stored in all the
addresses from the base address to the entered address will be displayed (refer
to examples 3 and 4.)
New data can be stored in memory as well; this data will overwrite existing data.
Input data must be in hexadecimal. Upper case characters must be used for the
alphanumeric values of A to F (hex). When the leftmost digit is a “0”, it can be
omitted.
There are two ways to poke data (directly store data to a specific address).
1, 2, 3...
1.
Specify the first address followed by a colon. Directly after the colon, enter
the data (1 or 2 byte hexadecimal values only) separated by spaces. Then
type a carriage return (refer to example 5.)
2.
Enter a colon followed by the data and type a carriage return. Data will be
stored starting from the base address (refer to example 6.)
