No. 26 Regarding hot plug-in function

[Description]

The OCD does not support the hot plug-in function.

[Resolution]

None

When hot plug-in may be used in the future, it is necessary to make it the following circuit configurations.

As shown at Figure A, because 4.7uF capacitor is fixed with 8th pin of E1/E20 emulator inside, power supply

voltage in user system may decrease for an instant when it is in hot-plug connecting. This decrease in voltage

might lead MCU to be reset.

By fixing Ferrite Beads ( or inductor) and large-sized low ESR capacitor with an area close to VDD line of debug

connector ,as shown at Figure B, it is able to reduce the value of the voltage to the minimum. However, it is not

the solution that completely prevent it.

In addition, hot plug-in function is valid only for debugging.

Hot plug-in adapter(option) is required to use this function.

Support schedule of a hot plug-in function is T.B.D.
