The emulator is placed in the forced reset state by short-circuiting the emulator reset header (EJ2). At this time, remove SS5 and make EJ1 open-circuit. This allows stand-alone operation of the RL78/G1N independently of control by the IDE while the IDE is applying a forcible reset. Figure 5-2 shows the position of the emulator reset headers (EJ2, EJ1, and SS5) (only through-holes are provided;... -
Page 17: Power-Supply Selection Header
Power-Supply Selection Header The operating voltage of the RL78/G1N can be changed to VBUS (5 V) or 3.3 V with the use of this header (J5). Figure 5-3 shows the connection of the header for VBUS (5-V) output, and Figure 5-4 shows the connection of the header for 3.3-V output. -
Page 18: External Power-Supply Header
5.11 External Power-Supply Header When operating the RL78/G1N at a desired external input voltage, or when more current is required than the USB is capable of supplying, use the external power-supply header (J4) to supply power. The usable voltage range is from 2.25 V to 5.5 V. -
