de (data memory enter)
Function
This command rewrites the contents of the data memory with the input hexadecimal data. Data can
be written to continuous memory locations beginning with a specified address.
Format
(1) >de <address> <data1> [<data2> [...<data16>]]↵ (direct input mode)
(2) >de↵ (guidance mode)
Data enter address ? <address>↵
Address Original data
: <data>↵
..........
>
<address>: Start address from which to write data; hexadecimal or symbol (IEEE-695 format only)
<data(1–16)>: Write data; hexadecimal
Condition: 0 ≤ address ≤ last data memory address, 0 ≤ data ≤ 0xf
Examples
Format (1)
>de 100 A↵ ... Rewrites data at address 0x100 with 0xa.
Format (2)
>de↵
Data enter address ? 100↵ ... Address is input.
100 0 : a↵ ... Data is input.
101 0 : ↵ ... Skipped.
102 0 : q↵ ... Command is terminated.

Notes
• The start address specified here must be within the range of the data memory area available with each
microcomputer model.
An error results if the input one is not a hexadecimal number or a valid symbol.
Error : invalid value.
An error results if the limit is exceeded.
Error : Data address out of range.
• The contents of the read only area cannot be rewritten. A warning message will be displayed if you
specify such an address.
Warning : read only address, can't write.
• In guidance mode, the contents of the write-only I/O area will be marked as hyphens (-).
For the contents of address of mixed read-only and write-only bits in I/O area, an exclamation mark
(!) will be marked in front of the data.
The contents of the unused area will be marked as slashes (/). If you encounter any address marked
by "/", press [Enter] key to skip that address or terminate the command.
• Data must be input using a hexadecimal number in the range of 4 bits (0 to 0xf). An error results if the
limit is exceeded.
Error : Data out of range, use 0-0xf.
•When the contents of the data memory is modified using the de command, the displayed contents of
the [Data] window are updated automatically.
