connect the FLMD0 signal as shown in Figure 3-8.
Figure 3-8. Example Connection of FLMD0 Pin When Performing Flash Self Programming
Remark The resistance of R2 must be at least 10 times the resistance of R1.
When leaving the FLMD0 signal output from QB-V850MINIL or QB-V850MINI open and connecting a port signal to
FLMD0 on the target device, set the output of the port to high level in the SFR or other debugger window when writing
to the flash memory during a break. When not writing to the flash memory, set the port output to low level or set the
port to input mode.
