When the
x
command is executed once, you can dump and display a single unit of data (having the same size
as that of the previous address) from the address following the previous address by simply entering
x
.

When specifying an address with a data symbol that references the assigned address, add
&
when you enter the
command. When only specifying a symbol, note that its data value is used as the address. In such case,
&
need
not be added because labels in program code indicate assigned addresses.
GUI
The contents of memory can be confirmed in the [Memory] window. (See 10.4.5, "[Memory] Window".)
Notes
• Memory contents are displayed in little endian format. However, when debugging a program in simulator
mode, you can set a specified area to big endian format in a parameter file.
• Even when an unused area of memory is specified, no errors are assumed. However, the displayed data is not
valid.
• Even if the specified address is not a boundary address conforming to the data size, the
x
command starts
displaying memory contents from that address.
• If the specified address exceeds the 24-bit range, an error is assumed.
• Executing this command does not affect the [Memory] window.
