ew (enter word)
This command rewrites the contents of the memory with the entered word data (hexadecimal).
Data can be written to continuous memory locations beginning with a specified address, according to guidance
mode. The memory is rewritten in the endian format specified with the parameter file (default: little endian).

(2) ew <address>
Addresses and current data are displayed as guidance.

Notes
Since data is rewritten in units of 32 bits, specify a word boundary address for the start addresses. If an invalid
address is specified, a warning is generated and the two least significant bits of the specified address is
rewritten to 0.
The start address specified here must be within the range of 0 to 0xfffffff. An error results if this limit is
exceeded. In Format 1, guidance is displayed to prompt you to input an address again. In Format 2, your
command input is canceled.
For unused addresses in the memory map, data is marked by "********" as displayed on the screen. Although
it is possible to specify an unused address or display guidance, entering data in this case results in an error. If
you encounter any address marked by "********", hit the [Enter] key to skip that address or terminate the
command.
Data must be input by using a hexadecimal number in the range of 16 bits (0 to 0xffffffff). An error results if
this limit is exceeded. Guidance is displayed to prompt you to input data at the same address again.
During guidance-assisted input, the addresses are not changed even when you perform an operation to move
to an address ahead of address 0 or an operation that results in exceeding address 0xfffffff.
The ew command does not update the display contents of the [Memory] and [Source] windows. To update the
display contents, redisplay the window with the display command or scroll the window in the vertical direction.
The source displayed in the [Source] window remain unchanged even if the program area is rewritten.
<address>: Start address from which to write data (hexadecimal or symbol)
Conditions: 0
In both of these examples, the content of address 0x0 (to 0x3) is rewritten with data 0x12345678 (in
case of little endian format).
Warning: Round down to multiple of 4.
Error: Address range (0-0xFFFFFFF).
Error: No map area.
Error: Data range (0-0xFFFFFFFF).
