CHAPTER 16: DEBUGGER
eh (enter half)
This command rewrites the contents of the memory with the entered half 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) eh <address>
Addresses and current data are displayed as guidance.

Notes
Since data is rewritten in units of 16 bits, specify a half word boundary address (even address) for the start
address. If odd address is specified, a warning is generated and the LSB 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 0xffff). 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 eh 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 0x1) is rewritten with data 0x1234 (in case
of little endian format).
Warning: Round down to multiple of 2.
Error: Address range (0-0xFFFFFFF).
Error: No map area.
Error: Data range (0-0xFFFF).
