16.10.13 Simulated I/O
stdin (standard input)
This command sets up the environment necessary to input data from the [Simulated I/O] window or a file, and
pass it on to the program. Use this command to set up the following conditions:
For preparation on the program side, refer to Section 16.9.8, "Simulated I/O".
436
(1) Setting
(2) Clearing
Break address (a position at which the db33 takes in data)
Input buffer address (a 65-byte buffer)
Input device ([Simulated I/O] window or a file)
Function
Format
Input examples
Notes
The break address you set in the stdin command cannot overlap any software PC breakpoint. In such a case,
clear the software PC breakpoint before you execute the stdin command. Overlapping with a hardware PC
breakpoint is accepted.
The break and buffer addresses must be specified within the range of the memory area available for each
microcomputer model. An error results if this limit is exceeded. In this case, the system brings up a guidance
for entering addresses again.
When using the simulated I/O function in ICE mode, the display response time is improved by setting the
baud rate to 115200bps and the on-the-fly interval to 0 (md command).
stdin
If the program is run continuously after setting up the above, the db33 stops executing at the position of a
label READ_FLASH in the program, and brings up the [Simulated I/O] window. When you input data in
the window and press the [Enter] key, the db33 takes in the input data into the input buffer (READ_BUF),
then restarts executing the program.
If you chose "2. file" in the input mode, input a file name too.
If you chose a file for the input source, the db33 takes in one line of data from a specified file at the break
position without bringing up the [Simulated I/O] window.
To terminate command execution, input only the [Enter] key in the middle of guidance.
The data input function is deactivated.
Error: Address range (0-0xFFFFFFF).
Error: No map area.
