FLMD0
This is the flash mode signal. It is used only when the target device incorporates flash memory.
The flash self-programming function is used for the download function for downloading to the flash memory using
the integrated debugger. The FLMD0 pin must be made high level during flash self-programming.
There are two methods for controlling the FLMD0 pin from the IE-V850E1-CD-NW. Either one can be selected for
use.
<1> Control from IE-V850E1-CD-NW
Connect the FLMD0 pin from the IE-V850E1-CD-NW to the FLMD0 pin of the target device.
In the normal mode, nothing is driven from the IE-V850E1-CD-NW.
When, during a break, the download function, etc., of the integrated debugger is executed, the FLMD0 pin
from the IE-V850E1-CD-NW is controlled to be high level. Barring a problem arising from the specifications,
pull down the FLMD0 pin to low level.

<2> Control from port
Connect an unused port of the target device to the FLMD0 pin.
The same port pin (PORT in Figure 3-7) can be used with no problem to realize the flash self-programming
function in the user program using a similar method. Barring a problem arising from the specifications, pull
down this pin to low level.
Perform settings to make the port pin high level prior to executing the download function and make the port
pin low level or high impedance after executing the download function, through the integrated debugger
console. (For details, refer to the
ID850NWC Integrated Debugger Ver. 2.51 or Later Operation
(Windows Based) User’s Manual (U16525E)
