Notes on the USB Connector:
In the factory-setting, electrical characteristics differ from those of the actual MCU because of
the flexible cable between the emulation MCU and target system. If there are problems with
electrical characteristics because of the flexible cable, the USB connector on the emulation pod
can be used.
• Pin 1 of the USB connector connects only to the test pin (USB_VCC) located near
the USB connector.
• When the USB connector is used, pins D+ and Ext. Cap are connected in the
emulation pod through a 1.5K resistance.
