2.4.2. External Power Stage Interface
Since internal power stage allows only the management of low voltage / low current motors, an interface with
an external power stage is provided. This allows the RL78/G14 MCU together with the control GUI or IDE
debugger to control a high voltage high power motor via a suitable external inverter unit.
Please find below the signal connection interface for the external power stage interface connector J10.
