Figure 51. Insertion of 200 Ohms in VPP Line
NOTES:
1. If other signals affect communication in ISP mode, disconnect them from the pins (DSDA/DSCL) using a
jumper or switch.
2. A 200Ω resistor must be installed at the target board. Without it, an MCU can be damaged because of a
high voltage (17.0V). To remove it, users need to insert it in the Vpp line of the ISP cable as illustrated
below:
