Note on CNVSS:
•To debug the control program for CPU rewrite mode, you need to apply 4.5 to 5.5
V voltage to the CNVSS pin.
When the target system is connected:
Set the jumper switch JP1 of the M30220TF-PRB to "CNVSS". The CNVSS is
connected to the target system. Apply 4.5V to 5.5V voltage to the CNVSS pin of the
target system.
When the target system is NOT connected:
Set the jumper switch JP1 of the M30220TF-PRB to "VDD". 5V voltage is applied
from the emulation pod to the CNVSS.
