resistance: 100 Ω or less). For details, refer to 4.1.3 Connection of reset pin of QB-MINI2 On-Chip Debug
Emulator with Programming Function (18371E).
To prevent an oscillation circuit from not oscillating due to wiring capacitance when the target device operates
(when QB-MINI2 is not connected), also consider countermeasures such as disconnecting the oscillation circuit
from the target connectors by setting the jumpers.
A program that was downloaded using the debugger does not operate when QB-MINI2 is not connected.
30 mm from the QB-MINI2 connectors or the paths must be shielded by connecting them to GND.
